Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 461475

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: dm log: fix out-of-bounds write due to
 region_count overflow The local variable region_count in create_log_context() is declared as unsigned int
 (32-bit), but dm_sector_div_up() returns sector_t (64-bit). When a device-mapper target has a sufficiently
 large ti->len with a small region_size, the division result can exceed UINT_MAX. The truncated value is
 then used to calculate bitset_size, causing clean_bits, sync_bits, and recovering_bits to be allocated far
 smaller than needed for the actual number of regions. Subsequent log operations (log_set_bit,
 log_clear_bit, log_test_bit) use region indices derived from the full untruncated region space, causing
 out-of-bounds writes to kernel heap memory allocated by vmalloc. This can be reproduced by creating a
 mirror target whose region_count overflows 32 bits: dmsetup create bigzero --table '0 8589934594 zero'
 dmsetup create mymirror --table '0 8589934594 mirror \ core 2 2 nosync 2 /dev/mapper/bigzero 0 \
 /dev/mapper/bigzero 0' The status output confirms the truncation (sync_count=1 instead of 4294967297,
 because 0x100000001 was truncated to 1): $ dmsetup status mymirror 0 8589934594 mirror 2 254:1 254:1
 1/4294967297 ... This leads to a kernel crash in core_in_sync: BUG: scheduling while atomic: (udev-
 worker)/9150/0x00000000 RIP: 0010:core_in_sync+0x14/0x30 [dm_log] CR2: 0000000000000008 Fixing recursive
 fault but reboot is needed! Fix by widening the local region_count to sector_t and adding an explicit
 overflow check before the value is assigned to lc->region_count. (CVE-2026-53059)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
