Astra Linux - Vulnerability in Linux

A vulnerability was discovered in the Linux kernel versions 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where multiple operations are performed in a single hypercall; the success or failure of each operation is reported to the backend driver, whi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: powerpc/fixmap: Fixed the VM debug warning when unmapping a fixmap entry. The unmapping of a fixmap entry is performed by calling setfixmap, with FIXMAPPAGECLEAR as the flag. Currently, powerpc setfixmap calls mapkernelpage...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: ecbhf: Fixed the dmafreecoherent function’s DMA handle. The error-prone use of dmafreecoherent takes priv-rxbuf.alloclen as the DMA handle. This could result in improper unmapping of the buffer. The DMA handle has...

UBUNTU-CVE-2026-72038

In the Linux kernel, the following vulnerability has been resolved: net: liquidio: fix BAR resource leak on PF number failure If cn23xxgetpfnum fails, the function returns without unmapping either BAR. Unmap both BARs before returning from the error path. Found by manual code review...

CVE-2026-74280

The CVE-2026-74280 entry concerns the Linux kernel crypto: marvell/octeontx component where DMA cleanup used the wrong loop index. Specifically, the sg_cleanup path unmaps DMA buffers using list[i] instead of list[j], leading to leaking successfully mapped entries and repeatedly unmapping the fai...

CVE-2026-74279 crypto: cavium/cpt - fix DMA cleanup using wrong loop index

In the Linux kernel, the following vulnerability has been resolved: crypto: cavium/cpt - fix DMA cleanup using wrong loop index The sgcleanup error path used listi instead of listj when unmapping DMA buffers, leaking successfully mapped entries and repeatedly unmapping the failed one...

CVE-2026-72291

CVE-2026-72291 : In the Linux kernel (KVM for s390), a fix was applied for an unlikely race in try_get_locked_pte() that could occur if puds or pmds are unmapped between p?dp_get() and p?d_offset() calls. The issue affects the page-table handling path and is mitigated by the update; affected comp...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: fix indefinite fence wait during GPU reset prereset only force-completes fences of MAPPED queues. A queue in any other state e.g. mid-eviction keeps its lastfence pending; after a GPU reset that fence never...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: USB: uas: Fixing the URB unmapping issue when the UAS device is removed during ongoing data transfer When a UAS device is unplugged during data transfer, there is a possibility of a system panic occurring. The root cause is...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: accel/ivpu: Fixed a race condition when unbinding BOs. Fixed a warning stating “Memory manager not cleaned during takedown” that occurs when ivpugembofree removes a BO from the BOs list before it is unmapped. This issue caused...
