kernel: udp: do not accept non-tunnel GSO skbs landing in a tunnel
CVE-2024-35884 highlights a flaw in the Linux kernel's handling of UDP packets when Generic Receive Offload GRO forwarding is enabled. The issue occurs because non-tunnel UDP packets are sometimes mistakenly processed as if they belong to a tunnel. This can lead to data corruption or kernel...

kernel: gro: fix ownership transfer
A flaw was found in the Linux kernel's Generic Receive Offload GRO feature, where packets processed with a fragment list are not properly orphaned due to incorrect handling of socket references. This vulnerability can cause system instability or kernel bugs. The issue has been fixed by making sur...

SUSE CVE-2024-35884
In the Linux kernel, the following vulnerability has been resolved: udp: do not accept non-tunnel GSO skbs landing in a tunnel When rx-udp-gro-forwarding is enabled UDP packets might be GROed when being forwarded. If such packets might land in a tunnel this can cause various issues and...
DEBIAN-CVE-2024-35890
In the Linux kernel, the following vulnerability has been resolved: gro: fix ownership transfer If packets are GROed with fraglist they might be segmented later on and continue their journey in the stack. In skbsegmentlist those skbs can be reused as-is. This is an issue as their destructor was...
