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

In the Linux kernel, the following vulnerabilities have been resolved: ipv6: Rejected malicious packets in ipv6gsoSegment. syzbot was able to create a packet with very long IPv6 extension headers, leading to an overflow of skb-transportheader. This 16-bit field has a limited range. Add the...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: net: gso: fix ownership in udpgsosegment In udpgsosegment, the skb destructor is removed prior to segmenting the skb, but the socket reference remains intact. This becomes problematic if the original skb ends up orphaned, as this...

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

In the Linux kernel, the following vulnerability has been resolved: net: nsh: Use the correct macoffset to unwind gso skb in nshgsoSegment. As shown in the call trace, the skbpanic error occurred due to an incorrect skb-macheader in nshgsoSegment. Invalid opcode: 0000 1 PREEMPT SMP KASAN PTI CPU:...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...
