CVE-2026-63918

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol l2tp module. A race condition exists where a network session's memory could be prematurely released while still in use. This vulnerability, caused by incorrect reference counting, may allow a local attacker to trigger a system cras...

SUSE CVE-2026-63946

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix UAF in isorecvframe isorecvframe reads conn-sk under isoconnlock but releases the lock before using sk, with no reference held. A concurrent isosockkill can free sk in that window, causing use-after-free on...

SUSE CVE-2026-64044

In the Linux kernel, the following vulnerability has been resolved: ovpn: respect peer refcount in CMDNEWPEER error path ovpnnlpeernewdoit's error path calls ovpnpeerrelease directly rather than ovpnpeerput, bypassing the kref. The accompanying comment "peer was not yet hashed, thus it is not use...

Important: vim

Issue Overview: Vim is an open source, command line text editor. Prior to 9.2.0653, the treecountwords function in src/spellfile.c fills in the word-count fields of a spell-file word trie by walking it iteratively with a depth counter. The counter is bounded only by the trie structure itself; it ...

CVE-2026-64147

In the Linux kernel, the following vulnerability has been resolved: pdscore: fix debugfslookup dentry leak and error handling debugfslookup returns a dentry with an elevated reference count that must be released with dput. The current code discards the returned dentry without calling dput, causin...

CVE-2026-64044

Concrete details confirm CVE-2026-64044 fix in the Linux kernel’s OpenVPN peer handling. The error path in ovpn_nl_peer_new_doit() previously called ovpn_peer_release() directly instead of ovpn_peer_put(), bypassing the kref, risking use-after-free when a caller holds a ref during an in-flight op...

EUVD-2026-45752

In the Linux kernel, the following vulnerability has been resolved: net/handshake: hand off the pinned file reference to acceptdoit handshakereqnext removes the request from the per-net pending list and drops hnlock before handshakenlacceptdoit reads req-hrsk-sksocket and dereferences sock-file...

CVE-2026-63946

CVE-2026-63946: In the Linux kernel Bluetooth ISO path, iso_recv_frame can use a freed sk due to holding iso_conn_lock but releasing it before using conn->sk. The fix replaces a bare pointer read with iso_sock_hold(conn), which holds the sock while the spinlock is still held and atomically inc...

CVE-2026-63919 xfrm: input: hold netns during deferred transport reinjection

In the Linux kernel, the following vulnerability has been resolved: xfrm: input: hold netns during deferred transport reinjection Transport-mode reinjection stores a struct net pointer in skb-cb and uses it later from xfrmtransreinject. That pointer must stay valid until the deferred callback run...

EUVD-2026-45691

In the Linux kernel, the following vulnerability has been resolved: l2tp: use refcountincnotzero in l2tpsessiongetbyifname A reader in l2tpsessiongetbyifname can return a pointer to a session whose refcount has reached zero. The getter takes its reference with plain refcountinc, but every other...

CVE-2026-63918

CVE-2026-63918 documents a Linux kernel fix: l2tp_session_get_by_ifname previously used refcount_inc() while other getters used refcount_inc_not_zero(), risking use-after-free if a race during RC/Rcu grace period allowed a zero refcount. The change normalizes the getter to refcount_inc_not_zero()...

CVE-2026-63827

Root cause: Linux kernel AppArmor uses a use-after-free in the rawdata dedup loop (aa_replace_profiles) due to unsafe refcount handling when traversing ns->rawdata_list. The dedup path calls aa_get_profile_loaddata() which has plain kref_get() semantics, allowing a zero counter to be dereferen...
