Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the packet function, there is a need to use a consistent value for hardheaderlen in non-ring send paths. The packetsnd function reads dev-hardheaderlen multiple times during allocation and construction of an skb. Device...

kernel: packet: use consistent hard_header_len in non-ring send paths

An out-of-bounds write problem was observed in packetsendmsgspkt in net/packet/afpacket.c in the Linux Kernel. In this flaw, AFPACKET hardheaderlen race may allow local privilege escalation...
