SCSI does not set GD_OWNS_QUEUE, so QUEUE_FLAG_DYING is not set in
this scenario. This is a classic ABBA deadlock. To fix the deadlock,
make sure we don't try to acquire disk->open_mutex after freezing
the queue.

Title
mm/mglru: fix div-by-zero in vmpressure_calc_level()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/mglru: fix div-by-zero in vmpressure_calc_level()
evict_folios() uses a second pass to reclaim folios that have gone through
page writeback and become clean before it finishes the first pass, since
folio_rotate_reclaimable() cannot handle those folios due to the
isolation.
The second pass tries to avoid potential double counting by deducting
scan_control->nr_scanned. However, this can result in underflow of
nr_scanned, under a condition where shrink_folio_list() does not increment
nr_scanned, i.e., when folio_trylock() fails.
The underflow can cause the divisor, i.e., scale=scanned+reclaimed in
vmpressure_calc_level(), to become zero, resulting in the following crash:
[exception RIP: vmpressure_work_fn+101]
process_one_work at ffffffffa3313f2b
Since scan_control->nr_scanned has no established semantics, the potential
double counting has minimal risks. Therefore, fix the problem by not
deducting scan_control->nr_scanned in evict_folios().

Title
net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE
The following splat is easy to reproduce upstream as well as in -stable
kernels. Florian Westphal provided the following commit:
d1dab4f71d37 ("net: add and use __skb_get_hash_symmetric_net")
but this complementary fix has been also suggested by Willem de Bruijn
and it can be easily backported to -stable kernel which consists in
using DEBUG_NET_WARN_ON_ONCE instead to silence the following splat
given __skb_get_hash() is used by the nftables tracing infrastructure to
to identify packets in traces.

Title
dm-raid: Fix WARN_ON_ONCE check for sync_thread in raid_resume
Summary
In the Linux kernel, the following vulnerability has been resolved:
dm-raid: Fix WARN_ON_ONCE check for sync_thread in raid_resume
rm-raid devices will occasionally trigger the following warning when
being resumed after a table load because DM_RECOVERY_RUNNING is set:
WARNING: CPU: 7 PID: 5660 at drivers/md/dm-raid.c:4105 raid_resume+0xee/0x100 [dm_raid]
The failing check is:
WARN_ON_ONCE(test_bit(MD_RECOVERY_RUNNING, &mddev->recovery));
This check is designed to make sure that the sync thread isn't
registered, but md_check_recovery can set MD_RECOVERY_RUNNING without
the sync_thread ever getting registered. Instead of checking if
MD_RECOVERY_RUNNING is set, check if sync_thread is non-NULL.

Title
scsi: lpfc: Fix a possible null pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix a possible null pointer dereference
In function lpfc_xcvr_data_show, the memory allocation with kmalloc might
fail, thereby making rdp_context a null pointer. In the following context
and functions that use this pointer, there are dereferencing operations,
leading to null pointer dereference.
To fix this issue, a null pointer check should be added. If it is null,
use scnprintf to notify the user and return len.

No CVSS data available.

In the Linux kernel, the following vulnerability has been resolved:
PCI: keystone: Fix NULL pointer dereference in case of DT error in ks_pcie_setup_rc_app_regs()
If IORESOURCE_MEM is not provided in Device Tree due to
any error, resource_list_first_type() will return NULL and
pci_parse_request_of_pci_ranges() will just emit a warning.
This will cause a NULL pointer dereference. Fix this bug by adding NULL
return check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (adc128d818) Fix underflows seen when writing limit attributes
DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large
negative number such as -9223372036854775808 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

Title
uprobe: avoid out-of-bounds memory access of fetching args
Summary
In the Linux kernel, the following vulnerability has been resolved:
uprobe: avoid out-of-bounds memory access of fetching args
Uprobe needs to fetch args into a percpu buffer, and then copy to ring
buffer to avoid non-atomic context problem.
Sometimes user-space strings, arrays can be very large, but the size of
percpu buffer is only page size. And store_trace_args() won't check
whether these data exceeds a single page or not, caused out-of-bounds
memory access.
It could be reproduced by following steps:
1. build kernel with CONFIG_KASAN enabled
2. save follow program as test.c
```
\#include <stdio.h>
\#include <stdlib.h>
\#include <string.h>
// If string length large than MAX_STRING_SIZE, the fetch_store_strlen()
// will return 0, cause __get_data_size() return shorter size, and
// store_trace_args() will not trigger out-of-bounds access.
// So make string length less than 4096.
\#define STRLEN 4093
void generate_string(char *str, int n)
{
int i;
for (i = 0; i < n; ++i)
{
char c = i % 26 + 'a';
str[i] = c;
}
str[n-1] = '\0';
}
void print_string(char *str)
{
printf("%s\n", str);
}
int main()
{
char tmp[STRLEN];
generate_string(tmp, STRLEN);
print_string(tmp);
return 0;
}
```
3. compile program
`gcc -o test test.c`
4. get the offset of `print_string()`
```
objdump -t test | grep -w print_string
0000000000401199 g F .text 000000000000001b print_string
```
5. configure uprobe with offset 0x1199
```
off=0x1199
cd /sys/kernel/debug/tracing/
echo "p /root/test:${off} arg1=+0(%di):ustring arg2=\$comm arg3=+0(%di):ustring"
> uprobe_events
echo 1 > events/uprobes/enable
echo 1 > tracing_on
```
6. run `test`, and kasan will report error.

Some deployments also grant tracefs write access to a non-root tracing group.\nUI:N - The attacker triggers the bug by running the instrumented binary itself with long string arguments; no victim action is required as part of the attack.\nS:U - The corruption stays within the kernel\u0027s own security authority \u2014 standard local privilege escalation, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - The perf path memcpy\u0027s up to ~4 KB beyond the per-CPU page into trace records, disclosing adjacent kernel memory, and the controlled OOB write is readily leveraged into an arbitrary-read primitive by corrupting neighboring kernel objects.\nI:H - This is an out-of-bounds write with attacker-chosen length and fully attacker-chosen bytes past a page-sized buffer, corrupting whatever adjacent buddy page holds (slab objects, page tables, stacks) \u2014 a direct path to control-flow hijack and privilege escalation.\nA:H - Smashing adjacent kernel pages with arbitrary user data reliably produces oopses and panics, as demonstrated by the KASAN splat in the fix commit, and the attacker can repeat it at will."

Title
Apache Tomcat: RCE due to TOCTOU issue in JSP compilation
Summary
Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP compilation in Apache Tomcat permits an RCE on case insensitive file systems when the default servlet is enabled for write (non-default configuration).
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.2, 10.1.34 or 9.0.98, which fixes the issue.
