In the Linux kernel, the following vulnerability has been resolved: batman-adv: The unmanaged ELP worker is removed. The ELP worker needs to calculate new metric values for all “reachable” neighbors via an interface. Some of the metric calculation functions require locks, which may need to be...

Astra Linux – Vulnerability in Linux 5.10

Ubuntu Linux 6.8, 6.17, and 7.0 contain AppArmor patches that incorrectly cause a sleep state when holding a spinlock in notification handling code. This bug can be triggered by an unprivileged local user, and can lead to kernel panic or deadlock situations...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys – fix a sleep while atomic with PREEMPTRT. When PREEMPTRT is enabled, the gpiokeysirqtimer callback runs in the hardirq context. However, the inputevent function takes a spinlock, which is not allowed in that...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fixed dtlaccesslock to use a rwsemaphore instead of a rwsemaphore. The dtlaccesslock needs to be a rwsemaphore, a sleeping lock, because the code calls kmalloc while holding it, which can cause a sleep condition:...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: clk: qcom: ipq8074: dont disable gccsleepclksrc Once the USB sleep clocks are disabled, the clock framework attempts to disable the sleep clock source as well. However, it seems that this attempt fails, resulting in the following...

There is a bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by simulating an NFC device from user-space...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: scsi: sg: Do not sleep in atomic context The function sgfinishremreq calls blkrqunmapuser. The latter function may sleep. Therefore, call sgfinishremreq with interrupts enabled instead of disabled...

Astra Linux – Vulnerability in edk2

EDK2 contains a vulnerability when the S3 sleep mechanism is activated. In this case, an attacker may cause a Division-by-Zero error due to a UNIT32 overflow through local access. Successful exploitation of this vulnerability could result in a loss of availability...

Astra Linux – Vulnerability in Samba

A vulnerability was discovered in Samba’s “rpcecho” development server, a non-Windows RPC server used to test Samba’s DCE/RPC stack components. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the “rpcecho” service operates with only one...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: drm/panel: ilitek-ili9881c: Fixed a warning related to GPIO controllers that need to sleep. The ilitek-ili9881c uses the non-sleeping gpiodsetvalue function to control the reset GPIO. This issue occurs when the GPIO controller...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: IB/mad: Do not call to functions that might sleep while in atomic context. Tracepoints are not allowed to sleep. As a result, the following error is generated due to a call to ibquerypkey in atomic context. WARNING: CPU: 0 PID:...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: renaming cpunumber1 to dummycpunumber. The per-process variable cpunumber1 is passed as an argument to xlnxeventhandler along with devid, but it is not used in this function. Therefore, the initialization of this...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Networks: TLS – Avoid hanging tasks when using txlock. The syzbot reported a situation where tasks were hung. Eric explains that the adversarial receiver may keep RWIN at 0 for a long time, so we cannot guarantee progress. Thread...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: hi311x: fix null pointer dereference when resuming from sleep before the interface was enabled. This issue is similar to the vulnerability in the mcp251x driver, which was fixed in commit 03c427147b2d “can: mcp251x: fix resu...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: tty: An option was added to allow a tty to reject a new ldisc. This allows us to limit the number of virtual terminals to just NTTY. These terminals are somewhat special; in particular, the “conwrite” routine violates the rule th...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RISCV: Fixed sleeping in an invalid context in die. Die can be called in an exception handler, and therefore cannot sleep. However, die takes spinlockt, which can sleep when PREEMPTRT is enabled. This causes the following warning...
