---[ end trace 0000000000000000 ]---
Kernel panic - not syncing: Fatal exception in interrupt
---[ end Kernel panic - not syncing: Fatal exception in interrupt ]---

This is a minimal userspace reproducer on a Raspberry Pi Zero W:

#include &lt;stdio.h&gt;
#include &lt;math.h&gt;

int main(void)
{
        double v = 1.0;
        printf(&quot;%fn&quot;, NAN + *(volatile double *)&amp;v);
        return 0;
}

Another way to consistently trigger the oops is:

calvin@raspberry-pi-zero-w ~$ python -c &quot;import json&quot;

The bug reproduces only when the kernel is built with DYNAMIC_DEBUG=n, because the pr_debug() calls act as barriers even when not activated.

This is the output from the same kernel source built with the same compiler and DYNAMIC_DEBUG=y, where the userspace reproducer works as expected:

VFP: bounce: trigger ec532b17 fpexc c0000780
VFP: emulate: INST=0xee377b06 SCR=0x00000000
VFP: bounce: trigger eef1fa10 fpexc c0000780

VFP: raising exceptions 30000000

calvin@raspberry-pi-zero-w ~$ ./vfp-reproducer
nan

Crudely grepping for vmsr/vmrs instructions in the otherwise nearly idential text for vfp_support_entry() makes the problem obvious:

vmlinux.llvm.good [0xc0101cb8] &lt;+48&gt;:  vmrs   r7, fpexc
vmlinux.llvm.good [0xc0101cd8] &lt;+80&gt;:  vmsr   fpexc, r0
vmlinux.llvm.good [0xc0101d20

---truncated---(CVE-2024-47716)

In the Linux kernel, the following vulnerability has been resolved:

bpf: check changes_pkt_data property for extension programs

When processing calls to global sub-programs, verifier decides whether to invalidate all packet pointers in current state depending on the changes_pkt_data property of the global sub-program.

Because of this, an extension program replacing a global sub-program must be compatible with changes_pkt_data property of the sub-program being replaced.

This commit: - adds changes_pkt_data flag to struct bpf_prog_aux: - this flag is set in check_cfg() for main sub-program; - in jit_subprogs() for other sub-programs; - modifies bpf_check_attach_btf_id() to check changes_pkt_data flag; - moves call to check_attach_btf_id() after the call to check_cfg(), because it needs changes_pkt_data flag to be set:

bpf_check:
  ...                             ...
- check_attach_btf_id             resolve_pseudo_ldimm64
  resolve_pseudo_ldimm64   --&gt;    bpf_prog_is_offloaded
  bpf_prog_is_offloaded           check_cfg
  check_cfg                     + check_attach_btf_id
  ...                             ...

efi: Don't map the entire mokvar table to determine its size

Currently, when validating the mokvar table, we (re)map the entire table on each iteration of the loop, adding space as we discover new entries. If the table grows over a certain size, this fails due to limitations of early_memmap(), and we get a failure and traceback:

Mapping the entire structure isn't actually necessary, as we don't ever need more than one entry header mapped at once.

Changes efi_mokvar_table_init() to only map each entry header, not the entire table, when determining the table size. Since we're not mapping any data past the variable name, it also changes the code to enforce that each variable name is NUL terminated, rather than attempting to verify it in place.(CVE-2025-21872)

In the Linux kernel, the following vulnerability has been resolved:

llc: do not use skb_get() before dev_queue_xmit()

syzbot is able to crash hosts [1], using llc and devices not supporting IFF_TX_SKB_SHARING.

In this case, e1000 driver calls eth_skb_pad(), while the skb is shared.

Simply replace skb_get() by skb_clone() in net/llc/llc_s_ac.c

Note that e1000 driver might have an issue with pktgen, because it does not clear IFF_TX_SKB_SHARING, this is an orthogonal change.

We need to audit other skb_get() uses in net/llc.

dm-flakey: Fix memory corruption in optional corrupt_bio_byte feature

Fix memory corruption due to incorrect parameter being passed to bio_init(CVE-2025-21966)

In the Linux kernel, the following vulnerability has been resolved:

md: fix mddev uaf while iterating all_mddevs list

While iterating all_mddevs list from md_notify_reboot() and md_exit(), list_for_each_entry_safe is used, and this can race with deletint the next mddev, causing UAF:

t1: spin_lock //list_for_each_entry_safe(mddev, n, ...) mddev_get(mddev1) // assume mddev2 is the next entry spin_unlock t2: //remove mddev2 ... mddev_free spin_lock list_del spin_unlock kfree(mddev2) mddev_put(mddev1) spin_lock //continue dereference mddev2->all_mddevs

The old helper for_each_mddev() actually grab the reference of mddev2 while holding the lock, to prevent from being freed. This problem can be fixed the same way, however, the code will be complex.

Hence switch to use list_for_each_entry, in this case mddev_put() can free the mddev1 and it's not safe as well. Refer to md_seq_show(), also factor out a helper mddev_put_locked() to fix this problem.(CVE-2025-22126)

In the Linux kernel, the following vulnerability has been resolved:

dlm: prevent NPD when writing a positive value to event_done

do_uevent returns the value written to event_done. In case it is a positive value, new_lockspace would undo all the work, and lockspace would not be set. __dlm_new_lockspace, however, would treat that positive value as a success due to commit 8511a2728ab8 ("dlm: fix use count with multiple joins").

Down the line, device_create_lockspace would pass that NULL lockspace to dlm_find_lockspace_local, leading to a NULL pointer dereference.

Treating such positive values as successes prevents the problem. Given this has been broken for so long, this is unlikely to break userspace expectations.(CVE-2025-23131)

In the Linux kernel, the following vulnerability has been resolved:

soc: samsung: exynos-chipid: Add NULL pointer check in exynos_chipid_probe()

soc_dev_attr->revision could be NULL, thus, a pointer check is added to prevent potential NULL pointer dereference. This is similar to the fix in commit 3027e7b15b02 ("ice: Fix some null pointer dereference issues in ice_ptp.c").

This issue is found by our static analysis tool.(CVE-2025-23148)

In the Linux kernel, the following vulnerability has been resolved:

media: venus: hfi_parser: refactor hfi packet parsing logic

words_count denotes the number of words in total payload, while data points to payload of various property within it. When words_count reaches last word, data can access memory beyond the total payload. This can lead to OOB access. With this patch, the utility api for handling individual properties now returns the size of data consumed. Accordingly remaining bytes are calculated before parsing the payload, thereby eliminates the OOB access possibilities.(CVE-2025-23156)

The actual device uninit usually happens on a separate thread scheduled after this code runs, but there is no guarantee of order of thread execution, so this could be a problem. There's no actual need to clear the client_id at this point, so simply remove the offending code.(CVE-2025-37916)

In the Linux kernel, the following vulnerability has been resolved:

vxlan: vnifilter: Fix unlocked deletion of default FDB entry

When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB entry associated with the default remote (assuming one was configured) is deleted without holding the hash lock. This is wrong and will result in a warning [1] being generated by the lockdep annotation that was added by commit ebe642067455 ("vxlan: Create wrappers for FDB lookup").

Reproducer:

# ip link add vx0 up type vxlan dstport 4789 external vnifilter local 192.0.2.1 # bridge vni add vni 10010 remote 198.51.100.1 dev vx0 # bridge vni del vni 10010 dev vx0

Fix by acquiring the hash lock before the deletion and releasing it afterwards. Blame the original commit that introduced the issue rather than the one that exposed it.

mm/huge_memory: fix dereferencing invalid pmd migration entry

When migrating a THP, concurrent access to the PMD migration entry during a deferred split scan can lead to an invalid address access, as illustrated below. To prevent this invalid access, it is necessary to check the PMD migration entry and return early. In this context, there is no need to use pmd_to_swp_entry and pfn_swap_entry_to_page to verify the equality of the target folio. Since the PMD migration entry is locked, it cannot be served as the target.

Mailing list discussion and explanation from Hugh Dickins: "An anon_vma lookup points to a location which may contain the folio of interest, but might instead contain another folio: and weeding out those other folios is precisely what the "folio != pmd_folio((*pmd)" check (and the "risk of replacing the wrong folio" comment a few lines above it) is for."

module: ensure that kobject_put() is safe for module type kobjects

In 'lookup_or_create_module_kobject()', an internal kobject is created using 'module_ktype'. So call to 'kobject_put()' on error handling path causes an attempt to use an uninitialized completion pointer in 'module_kobject_release()'. In this scenario, we just want to release kobject without an extra synchronization required for a regular module unloading process, so adding an extra check whether 'complete()' is actually required makes 'kobject_put()' safe.(CVE-2025-37995)

Refer to md_seq_show(), also factor\nout a helper mddev_put_locked() to fix this problem.(CVE-2025-22126)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\ndlm: prevent NPD when writing a positive value to event_done\n\ndo_uevent returns the value written to event_done. In case it is a\npositive value, new_lockspace would undo all the work, and lockspace\nwould not be set. __dlm_new_lockspace, however, would treat that\npositive value as a success due to commit 8511a2728ab8 (\u0026quot;dlm: fix use\ncount with multiple joins\u0026quot;).\n\nDown the line, device_create_lockspace would pass that NULL lockspace to\ndlm_find_lockspace_local, leading to a NULL pointer dereference.\n\nTreating such positive values as successes prevents the problem. Given\nthis has been broken for so long, this is unlikely to break userspace\nexpectations.(CVE-2025-23131)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nsoc: samsung: exynos-chipid: Add NULL pointer check in exynos_chipid_probe()\n\nsoc_dev_attr-\u0026gt;revision could be NULL, thus,\na pointer check is added to prevent potential NULL pointer dereference.\nThis is similar to the fix in commit 3027e7b15b02\n(\u0026quot;ice: Fix some null pointer dereference issues in ice_ptp.c\u0026quot;).\n\nThis issue is found by our static analysis tool.(CVE-2025-23148)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nmedia: venus: hfi_parser: refactor hfi packet parsing logic\n\nwords_count denotes the number of words in total payload, while data\npoints to payload of various property within it. When words_count\nreaches last word, data can access memory beyond the total payload. This\ncan lead to OOB access.

Since the PMD migration entry is locked, it\ncannot be served as the target.\n\nMailing list discussion and explanation from Hugh Dickins: \u0026quot;An anon_vma\nlookup points to a location which may contain the folio of interest, but\nmight instead contain another folio: and weeding out those other folios is\nprecisely what the \u0026quot;folio != pmd_folio((*pmd)\u0026quot; check (and the \u0026quot;risk of\nreplacing the wrong folio\u0026quot; comment a few lines above it) is for.\u0026quot;\n\nBUG: unable to handle page fault for address: ffffea60001db008\nCPU: 0 UID: 0 PID: 2199114 Comm: tee Not tainted 6.14.0+ #4 NONE\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\nRIP: 0010:split_huge_pmd_locked+0x3b5/0x2b60\nCall Trace:\n\u0026lt;TASK\u0026gt;\ntry_to_migrate_one+0x28c/0x3730\nrmap_walk_anon+0x4f6/0x770\nunmap_folio+0x196/0x1f0\nsplit_huge_page_to_list_to_order+0x9f6/0x1560\ndeferred_split_scan+0xac5/0x12a0\nshrinker_debugfs_scan_write+0x376/0x470\nfull_proxy_write+0x15c/0x220\nvfs_write+0x2fc/0xcb0\nksys_write+0x146/0x250\ndo_syscall_64+0x6a/0x120\nentry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nThe bug is found by syzkaller on an internal kernel, then confirmed on\nupstream.(CVE-2025-37958)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\niio: imu: st_lsm6dsx: fix possible lockup in st_lsm6dsx_read_tagged_fifo\n\nPrevent st_lsm6dsx_read_tagged_fifo from falling in an infinite loop in\ncase pattern_len is equal to zero and the device FIFO is not empty.(CVE-2025-37969)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nmodule: ensure that kobject_put() is safe for module type kobjects\n\nIn \u0026apos;lookup_or_create_module_kobject()\u0026apos;, an internal kobject is created\nusing \u0026apos;module_ktype\u0026apos;.
