CVE-2024-53097

CVE-2024-53097 affects the Linux kernel mm/krealloc path. Connected sources confirm a patch for mm: krealloc: Fix MTE false alarm in __do_krealloc, addressing a false KASAN/MTE slab-out-of-bounds error triggered when zeroing spare memory in __do_krealloc. Root cause: memory tagging mismatch due t...

CVE-2024-53097

In the Linux kernel, the following vulnerability has been resolved: mm: krealloc: Fix MTE false alarm in dokrealloc This patch addresses an issue introduced by commit 1a83a716ec233 "mm: krealloc: consider spare memory for GFPZERO" which causes MTE Memory Tagging Extension to falsely report a...

PT-2024-35560

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.65 Description The issue is related to a false alarm in the Memory Tagging Extension MTE caused by a mismatch between the pointer tag and the memory tag when zeroing out spare memory in do krealloc. This...

kernel: dma-buf/dma-resv: Stop leaking on krealloc() failure

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: Stop leaking on krealloc failure Currently dmaresvgetfences will leak the previously allocated array if the fence iteration got restarted and the kreallocarray fails. Free the old array by hand, and make sure we...

PT-2025-37545

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The dma resv get fences function in the Linux kernel may leak memory when krealloc array fails during fence iteration. This occurs because the previously allocated array is not freed, an...

kernel: ext4: fix potential memory leak in ext4_fc_record_regions()

In the Linux kernel, the following vulnerability has been resolved: ext4: fix potential memory leak in ext4fcrecordregions As krealloc may return NULL, in this case 'state-fcregions' may not be freed by krealloc, but 'state-fcregions' already set NULL. Then will lead to 'state-fcregions' memory...

kernel: Linux kernel (ext4): Memory leak due to improper handling of krealloc failure

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs due to improper handling of memory allocation failures when the krealloc function returns NULL within ext4fcrecordmodifiedinode. A local user could potentially exploit this flaw, leading to a memory leak. This memor...
