In the Linux kernel, the following vulnerability has been resolved: rxrpc: Don't move a peeked OOB message onto the pending queue rxrpc recvmsg oob takes a received oob message off recvmsg oobq and, if a response is needed, moves it onto the pending oobq tree. However, only the unlink from recvms...
CVE-2026-68302
In the Linux kernel, the following vulnerability has been resolved: amt: re-read skb header pointers after every pull Several AMT receive and transmit paths cache a pointer into the skb head iphdr, ipv6hdr, ethhdr or the AMT message header and then call a helper that can reallocate that head befo...
CVE-2026-68373

CVE-2026-52985
A flaw was found in the Linux kernel's netdevsim module. An uninitialized memory vulnerability exists in the handling of struct iphdr within a dummy skbuff due to the use of skbput instead of skbputzero. This could lead to unpredictable system behavior, including crashes Denial of Service, or...
CVE-2026-52985
In the Linux kernel, the following vulnerability has been resolved: netdevsim: zero initialize struct iphdr in dummy skbuff Syzbot reports a KMSAN uninit-value originating from nsimdevtrapskbbuild, with the allocation also being performed in the same function. Fix this by calling skbputzero inste...
CVE-2026-52985
CVE-2026-52985 concerns the Linux kernel in the netdevsim feature, where the IP header in a dummy skb was not zero-initialized in nsim_dev_trap_skb_build. The issue arises from using skb_put instead of skb_put_zero, leading to uninitialized values in the IP header and potential memory/safety impl...
CVE-2026-52985 netdevsim: zero initialize struct iphdr in dummy sk_buff

CVE-2026-46000 rxrpc: Fix conn-level packet handling to unshare RESPONSE packets
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix conn-level packet handling to unshare RESPONSE packets The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the skbuff may be shared with a packet sniffer, which would lead to...
CVE-2023-54039
The CVE-2023-54039 issue is in the Linux kernel’s CAN J1939 code, specifically j1939_tp_tx_dat_new(). The vulnerability arises when a memcpy uses skb->cb’s size, allowing an out-of-bounds read if skb->cb is larger than struct j1939_sk_buff_cb. The fix changes memcpy to use the size of struc...
