Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: perf/arm-cmn: Rejects unsupported hardware configurations. So far, we have been fairly lenient in accepting both unknown CMN models at least with a warning, as well as unknown revisions of those models that we do know about...

Astra Linux – Vulnerability in Firefox and Thunderbird

On arm64, an WASM brtable instruction with many entries could cause the label to be too far away from the instruction, leading to truncation and incorrect computation of the branch address. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1,...

Astra Linux – Vulnerability in Linux

There is an information disclosure vulnerability in the ARM SIGPAGE functionality of the Linux Kernel v5.4.66 and v5.4.54. The latest version 5.11-rc4 appears to still be vulnerable. A userland application can read the contents of the sigpage, which may lead to the exposure of kernel memory...

CVE-2026-74551

A flaw was found in the Linux kernel's hwmon: nzxt-smart2 driver. This vulnerability allows for immediate and deterministic memory corruption on systems with non-coherent CPU architectures, such as ARM or MIPS. When operations like setting a fan speed or updating an interval trigger a USB Direct...

EUVD-2026-60266

The ARM PL011 UART driver in drivers/serial/uartpl011.c fails to acknowledge receive error interrupts. On the PL011, the framing, parity, break, and overrun error interrupts PL011IMSCERRORMASK are cleared only by writing the interrupt-clear register UARTICR; reading the data register clears the R...

CVE-2026-12629 PL011 UART error interrupts never cleared, enabling an external-peer interrupt-storm denial of service

The ARM PL011 UART driver in drivers/serial/uartpl011.c fails to acknowledge receive error interrupts. On the PL011, the framing, parity, break, and overrun error interrupts PL011IMSCERRORMASK are cleared only by writing the interrupt-clear register UARTICR; reading the data register clears the R...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...
