SUSE CVE-2026-45990

In the Linux kernel, the following vulnerability has been resolved: slub: fix data loss and overflow in krealloc Commit 2cd8231796b5 "mm/slub: allow to set node and align in kvrealloc" introduced the ability to force a reallocation if the original object does not satisfy new alignment or NUMA nod...

CVE-2026-45990

A flaw was found in the Linux kernel. This vulnerability, a type of memory corruption, occurs within the krealloc and kvrealloc memory reallocation functions. When memory objects are resized or moved, these functions can incorrectly calculate the amount of data to copy, leading to an out-of-bound...

CVE-2026-45990

CVE-2026-45990 concerns the Linux kernel slub/kvrealloc code, where forcing realloc with new alignment/NUMA node could trigger data loss during NUMA migration and a potential out-of-bounds write when shrinking. The root cause described is that the reallocation path could memcpy with an incorrect ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking data upon a failure of krealloc. Currently, when dmaresvgetfences fails, it will leak the previously allocated array if the fence iteration was restarted and kreallocarray failed. The old array must...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mm: krealloc: Fixed an MTE false alarm in dokrealloc. This patch addresses an issue introduced by commit 1a83a716ec233, which caused MTE Memory Tagging Extension to falsely report a slab-out-of-bounds error. The problem occurs wh...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: a potential memory leak has been fixed in ext4fcrecordmodified inode. Since krealloc may return NULL, in this case, state-fcmodifiedinodes may not be freed by krealloc. However, state-fcmodifiedinodes is already set to NULL...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf, verifier: Fixed a memory leak in array reallocation for stack state. If an error NULL is returned by krealloc, callers of reallocarray would set their allocation pointers to NULL. However, when an error occurs in krealloc, i...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ext4: Fixed error handling in ext4fcrecordmodified inode. The current code does not properly handle the krealloc error case, which could lead to silent memory corruption or a kernel bug. This patch addresses this issue...
