CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-49960 – ext4: fix timer use-after-free on failed mount
https://notcve.org/view.php?id=CVE-2024-49960
In the Linux kernel, the following vulnerability has been resolved: ext4: fix timer use-after-free on failed mount Syzbot has found an ODEBUG bug in ext4_fill_super The del_timer_sync function cancels the s_err_report timer, which reminds about filesystem errors daily. We should guarantee the timer is no longer active before kfree(sbi). When filesystem mounting fails, the flow goes to failed_mount3, where an error occurs when ext4_stop_mmpd is called, causing a read I/O failure. This triggers the ext4_handle_error function that ultimately re-arms the timer, leaving the s_err_report timer active before kfree(sbi) is called. Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd. • https://git.kernel.org/stable/c/cf3196e5e2f36cd80dab91ffae402e13935724bc https://git.kernel.org/stable/c/9203817ba46ebba7c865c8de2aba399537b6e891 https://git.kernel.org/stable/c/fa78fb51d396f4f2f80f8e96a3b1516f394258be https://git.kernel.org/stable/c/b85569585d0154d4db1e4f9e3e6a4731d407feb0 https://git.kernel.org/stable/c/0ce160c5bdb67081a62293028dc85758a8efb22a •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-49940 – l2tp: prevent possible tunnel refcount underflow
https://notcve.org/view.php?id=CVE-2024-49940
In the Linux kernel, the following vulnerability has been resolved: l2tp: prevent possible tunnel refcount underflow When a session is created, it sets a backpointer to its tunnel. When the session refcount drops to 0, l2tp_session_free drops the tunnel refcount if session->tunnel is non-NULL. However, session->tunnel is set in l2tp_session_create, before the tunnel refcount is incremented by l2tp_session_register, which leaves a small window where session->tunnel is non-NULL when the tunnel refcount hasn't been bumped. Moving the assignment to l2tp_session_register is trivial but l2tp_session_create calls l2tp_session_set_header_len which uses session->tunnel to get the tunnel's encap. Add an encap arg to l2tp_session_set_header_len to avoid using session->tunnel. If l2tpv3 sessions have colliding IDs, it is possible for l2tp_v3_session_get to race with l2tp_session_register and fetch a session which doesn't yet have session->tunnel set. Add a check for this case. • https://git.kernel.org/stable/c/f7415e60c25a6108cd7955a20b2e66b6251ffe02 https://git.kernel.org/stable/c/24256415d18695b46da06c93135f5b51c548b950 •
