CVE-2026-53076

The CVE covers a Linux kernel BPF issue: an out-of-bounds read in pcpu_init_value when copying data between BPF_MAP_TYPE_CGROUP_STORAGE and a pcpu map with the same value_size that is not 8-byte aligned. The verifier reads the source size exactly, but the copy path sometimes rounds up to 8 bytes ...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Allow AppArmor to handle unaligned DFA tables. DFA tables can originate from the kernel or user space, and 8-byte alignment is not always guaranteed. This may lead to unaligned memory accesses on various architectures...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: AppArmor: Fixed and optimized the creation of tables from potentially unaligned memory. The source code may come from user space, and it might be unaligned. Try to optimize the copying process by avoiding unaligned memory...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: ath12k – Fix for the dmafreecoherent pointer. dmaalloccoherent allocates a DMA-mapped buffer and stores the addresses in XXXunaligned fields. These addresses should be reused when freeing the buffer, rather than using th...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: EFI: Fix for reserving unaccepted memory tables The reserveunaccepted function incorrectly calculates the size of the memblock reservation for the unaccepted memory tables. It aligns the size of the tables, but fails to take into...
