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 net: skbuff: preserve shared-frag marker during coalescing

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skbtrycoalesce can attach paged frags from @from to @to. If @from has SKBFLSHAREDFRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backe...

CVE-2026-46300

The CVE-2026-46300 issue affects the Linux kernel's net: skbuff code: skb_try_coalesce() can transfer paged frags from one skb to another while losing the SKBFL_SHARED_FRAG marker, breaking the invariant relied on by ESP decryption logic. This can allow an in-place decrypt path to operate on page...

CVE-2026-43503 net: skbuff: propagate shared-frag marker through frag-transfer helpers

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-frag marker through frag-transfer helpers Two frag-transfer helpers pskbcopyfclone and skbshift fail to propagate the SKBFLSHAREDFRAG bit in skbshinfo-flags when moving frags from source to...

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...
