kernel: can: raw: fix ro->uniq use-after-free in raw_rcv()

A flaw was found in the Linux kernel's Controller Area Network CAN raw socket implementation. A use-after-free vulnerability can occur due to a timing window during the unregistration of CAN receive filters, allowing a freed memory region to be accessed. This could lead to system instability or a...

rsync: Rsync: Use-after-free vulnerability in extended attribute handling

A flaw was found in rsync. When rsync is configured to handle extended attributes using the -X or --xattrs option, a remote attacker can exploit a use-after-free vulnerability. This occurs because the receivexattr function incorrectly processes an untrusted length value during a sorting operation...

CVE-2026-46300

CVE-2026-46300 ("Fragnesia") is a local privilege escalation in the Linux kernel's ESP/XFRM (IPsec ESP-in-TCP) subsystem. The root cause is that skb_try_coalesce() fails to propagate the SKBFL_SHARED_FRAG marker when transferring paged fragments, causing ESP to skip skb_cow_data() and decrypt in ...
