Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: netlink: afnetlink: Added a check on the len parameter to prevent empty skb objects. This prevents a division error in the netemenqueue function, which occurs when skb-len=0 and skb-datalen=0 during the randomized corruption...

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

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fix for u8 overflow By continuously sending L2CAPCONFREQ packets, chan-numconfrsp increases multiple times, eventually exceeding the maximum number i.e., 255. This patch prevents this issue by adding a bounda...

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-lib: Avoid division by zero in applyconstrainttosize The step variable is initialized to zero. It is changed during the loop, but if it isn’t changed, it will remain zero. Add a variable check before the division...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: bridge: Fixed a soft lockup issue in brmulticastqueryexpired. When setting multicastqueryinterval to a large value, the local variable time in brmulticastsendquery may overflow. If the time is less than a few milliseconds, t...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been fixed: ksmbd: Fixed an out-of-bounds write issue in smb2getea. smb2getea applies a 4-byte alignment padding using memset after writing each EA entry. The bounds check on buffreelen is performed before the memcpy operation, but the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv/sriov: Perform a null check on iov before dereferencing iov. Currently, the pointer iov is dereferenced before the null check of iov, which can lead to a null pointer dereference error. This issue is fixed by movi...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...
