kernel: net: netlink: af_netlink: Prevent empty skb by adding a check on len.
In the Linux kernel, the following vulnerability has been resolved: net: netlink: afnetlink: Prevent empty skb by adding a check on len. Adding a check on len parameter to avoid empty skb. This prevents a division error in netemenqueue function which is caused when skb-len=0 and skb-datalen=0 in...
kernel: bnxt: prevent skb UAF after handing over to PTP worker
A possible use-after-free after handing over to PTP worker was found in the Linux kernel. This may lead to a crash...
kernel: TIPC message reassembly use-after-free remote code execution vulnerability
A use-after-free UAF flaw exists in the Linux Kernel within the reassembly of fragmented TIPC messages, specifically in the tipcbufappend function. The issue results due to a lack of checks in the error handling cleanup and can trigger a UAF on "struct skbuff", which may lead to remote code...
kernel: net: amd-xgbe: Fix skb data length underflow
In the Linux kernel, the following vulnerability has been resolved: net: amd-xgbe: Fix skb data length underflow There will be BUGON triggered in include/linux/skbuff.h leading to intermittent kernel panic, when the skb length underflow is detected. Fix this by dropping the packet if such length...
kernel: nsh: Restore skb->{protocol,data,mac_header} for outer header in nsh_gso_segment().
In the Linux kernel, the following vulnerability has been resolved: nsh: Restore skb-protocol,data,macheader for outer header in nshgsosegment. syzbot triggered various splats see 0 and links by a crafted GSO packet of VIRTIONETHDRGSOUDP layering the following protocols: ETHP8021AD + ETHPNSH +...
