Astra Linux – Vulnerability in Linux, Linux 5.10

The Linux kernel may allow a local attacker to execute arbitrary code on the system, due to a concurrency use-after-free flaw in the badflpintr function. By executing a specially crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial-of-service...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: ca8210: Stop leaking the skb structure. Upon an error, the ieee802154xmitcomplete helper function is not called.

In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Rejecting out-of-bounds values in sndsocputvolsw We currently do not validate whether the values being set are within the range that we have advertised to userspace as valid. Instead, we reject any values that are out ...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: block: Fixed an incorrect offset in biotruncate The biotruncate function clears the buffer outside of the last block of bdev. However, the current implementation of biotruncate uses the wrong offset for the page. As a result, it...
