CVE-2026-46023

A flaw was found in the Linux kernel's device mapper dm mirror component. A local user could exploit an integer overflow vulnerability in the createdirtylog function by providing a specially crafted device mapper table string. This could lead to out-of-bounds reads, potentially causing system...

CVE-2026-46023

In the Linux kernel, the following vulnerability has been resolved: dm mirror: fix integer overflow in createdirtylog The argument count calculation in createdirtylog performs argsused = 2 + paramcount before validating against argc. When a user provides a paramcount close to UINTMAX via the devi...

CVE-2026-46023

CVE-2026-46023 is a Linux kernel vulnerability in dm-mirror where create_dirty_log() could bypass argc checks due to an unsigned add of 2 + param_count, allowing an out-of-bounds read in argv when param_count is near UINT_MAX. The root cause is an overflow in argument count calculation before val...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In the dmstats function, check for and propagate the allocpercpu failure. Check the return value of allocprecpu, and return an error from dmstatsinit if it fails. Update allocdev to fail if dmstatsinit does. Otherwise, a NULL...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: dm integrity: Memory corruption occurs when tagsize is less than digestsize. It is possible to configure dm-integrity in such a way that the tagsize parameter is smaller than the actual digestsize. In this case, a portion of the...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: dm: fixed a NULL pointer race issue when completing IO operations. The dmiodecpending function calls endioacct first, and then decreases the number of pending DMA operations. However, if a task swaps the DM table at the same...
