The Linux Kernel, the operating system core itself.

Security Fix(es):

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

gfs2: Fix possible data races in gfs2_show_options()

Some fields such as gt_logd_secs of the struct gfs2_tune are accessed without holding the lock gt_spin in gfs2_show_options():

val = sdp->sd_tune.gt_logd_secs; if (val != 30) seq_printf(s, ",commit=%d", val);

And thus can cause data races when gfs2_show_options() and other functions such as gfs2_reconfigure() are concurrently executed:

spin_lock(&gt->gt_spin); gt->gt_logd_secs = newargs->ar_commit;

To fix these possible data races, the lock sdp->sd_tune.gt_spin is acquired before accessing the fields of gfs2_tune and released after these accesses.

Further changes by Andreas:

• Don't hold the spin lock over the seq_printf operations.(CVE-2023-53622)

In the Linux kernel, a vulnerability exists in the IP checksum code for arm64 architecture. Although commit c2c24edb1d9c ("arm64: csum: Fix pathological zero-length calls") added an early return for zero-length input, syzkaller has discovered an example of a negative length that causes an undefined shift and an out-of-bounds read. An attacker can exploit this vulnerability to read data beyond the buffer boundary, affecting system confidentiality.(CVE-2023-53726)

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

SUNRPC: make sure cache entry active before cache_show

The function c_show was called with protection from RCU. This only ensures that cp will not be freed. Therefore, the reference count for cp can drop to zero, which will trigger a refcount use-after-free warning when cache_get is called. To resolve this issue, use cache_get_rcu to ensure that cp remains active.

In the Linux kernel, the following vulnerability has been resolved:dm array: fix releasing a faulty array block twice in dm_array_cursor_endWhen dm_bm_read_lock() fails due to locking or checksum errors, itreleases the faulty block implicitly while leaving an invalid outputpointer behind. The caller of dm_bm_read_lock() should not operate onthis invalid dm_block pointer, or it will lead to undefined result.For example, the dm_array_cursor incorrectly caches the invalid pointeron reading a faulty array block, causing a double release indm_array_cursor_end(), then hitting the BUG_ON in dm-bufio cache_put().Reproduce steps:1. initialize a cache devicedmsetup create cmeta --table 0 8192 linear /dev/sdc 0 dmsetup create cdata --table 0 65536 linear /dev/sdc 8192 dmsetup create corig --table 0 524288 linear /dev/sdc $262144 dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1dmsetup create cache --table 0 524288 cache /dev/mapper/cmeta /dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0 2. wipe the second array block offlinedmsteup remove cache cmeta cdata corigmapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 2>/dev/null | hexdump -e 1/8 %u n )ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) 2>/dev/null | hexdump -e 1/8 %u n )dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock3. try reopen the cache devicedmsetup create cmeta --table 0 8192 linear /dev/sdc 0 dmsetup create cdata --table 0 65536 linear /dev/sdc 8192 dmsetup create corig --table 0 524288 linear /dev/sdc…
