SUSE CVE-2023-52846

In the Linux kernel, the following vulnerability has been resolved: hsr: Prevent use after free in prpcreatetaggedframe The prpfillrct function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to f...

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-2021-47248

In the Linux kernel, the following vulnerability has been resolved: udp: fix race between close and udpabort Kaustubh reported and diagnosed a panic in udpliblookup. The root cause is udpabort racing with close. Both racing functions acquire the socket lock, but udpv6destroysock release it before...

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix UaF in listener shutdown As reported by Christoph after having refactored the passive socket initialization, the mptcp listener shutdown path is prone to an UaF issue. BUG: KASAN: use-after-free in...

kernel: x86/platform/uv: Use alternate source for socket to node data

In the Linux kernel, the following vulnerability has been resolved: x86/platform/uv: Use alternate source for socket to node data The UV code attempts to build a set of tables to allow it to do bidirectional socketnode lookups. But when nrcpus is set to a smaller number than actually present, the...

kernel: ip6_vti: fix slab-use-after-free in decode_session6

A use-after-free vulnerability was found in the IPv6 VTI Virtual Tunnel Interface implementation in the Linux kernel. When an IPv6 VTI device uses the SFB Stochastic Fair Blue qdisc, the control block cb field of an skb can be modified during packet enqueuing. The decodesession6 function then rea...

kernel: local dos vulnerability in scatterwalk_copychunks

A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their...

kernel: ipv4: NULL pointer dereference in ipv4_send_dest_unreach()

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...
