In the Linux kernel, the following vulnerabilities have been resolved: scsi: pm8001: Fix for aborting all task initialization In pm80xxsendabortall, the nelem field of the ccb used is not initialized to 0. This missing initialization sometimes causes the task completion path to encounter an ccb...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: xen/gntdev: Prevent leaking grants Prior to this commit, if a grant mapping operation failed partially, some of the entries in the mapops array would be invalid, while all of the entries in the kmapops array would be valid. This...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: safexcel – Added error handling for dmamapsg calls The macro dmamapsg function may return 0 in the event of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are...

kernel: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...

CVE-2026-89756

A flaw was found in the Linux kernel. When performing memory migration on KVM Kernel-based Virtual Machine hosts, the migratepagesbatch function fails to report RCU Read-Copy Update tasks quiescent states during large batch unmapping operations. This oversight causes the migrating task to become ...

CVE-2026-89593

CVE-2026-89593 affects the Linux kernel's hugetlb subsystem. Since commit df7a6d1f6405, the function __unmap_hugepage_range() can adjust reservations when a folio is mapped in both a parent and child process. If the parent unmaps the range first, the reservation adjustment causes an underflow of ...

CVE-2026-89593

In the Linux kernel, the following vulnerability has been resolved: hugetlb: only adjust reservation during unmapping if mapcount is 0 Since df7a6d1f6405, unmaphugepagerange can adjust reservations. In the case of folio mapped in both a parent and a child, if the parent unmaps the range first, th...
