kernel: tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp

In the Linux kernel, the following vulnerability has been resolved: tcp/udp: Fix memleaks of sk and zerocopy skbs with TX timestamp. syzkaller reported 0 memory leaks of an UDP socket and ZEROCOPY skbs. We can reproduce the problem with these sequences: sk = socketAFINET, SOCKDGRAM, 0...

Important: kernel-livepatch-5.10.165-143.735

Issue Overview: The upstream bug report describes this issue as follows: A flaw found in the Linux Kernel in RDS Reliable Datagram Sockets protocol. The rdsrmzerocopycallback uses listentry on the head of a list causing a type confusion. Local user can trigger this with rdsmessageput. Type...

Important: kernel

Issue Overview: A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L...

The vulnerability of the rds_rm_zerocopy_callback() function in the net/rds/message.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the rdsrmzerocopycallback function in the net/rds/message.c module of the Linux operating system is related to incorrect handling of the data block list. Exploiting this vulnerability could allow an attacker to cause a service failure...
