rh#2056830

An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in netfilter subcomponent in the Linux kernel due to a heap out of bounds write problem. In this flaw, an attacker with a user account on the system to gain access to out-of-bounds memory leads to a system crash or a privilege escalation threat.

Comment 1 Carlos López 2022-02-22 15:23:06 UTC

Affected branches:
 - master
 - stable
 - SLE15-SP4-GA
 - SLE15-SP3

The fix has not been merged to the upstream kernel yet.

Comment 4 Alexander Bergmann 2022-03-16 07:43:09 UTC

According to the oss-security post [1] and NIST page [2] this is only affecting kernel 5.4 through 5.6.10. Therefore only SLE-15-SP4 is/was affected.

Comment 6 Thomas Bogendoerfer 2022-03-16 08:48:18 UTC
