jira VULN-178540 cve CVE-2026-23243 commit-author YunJe Shin <yjshin0438@gmail.com> commit 5551b02 ib_umad_write computes data_len from user-controlled count and the MAD header sizes. With a mismatched user MAD header size and RMPP header length, data_len can become negative and reach ib_create_send_mad(). This can make the padding calculation exceed the segment size and trigger an out-of-bounds memset in alloc_send_rmpp_list(). Add an explicit check to reject negative data_len before creating the send buffer. KASAN splat: [ 211.363464] BUG: KASAN: slab-out-of-bounds in ib_create_send_mad+0xa01/0x11b0 [ 211.364077] Write of size 220 at addr ffff88800c3fa1f8 by task spray_thread/102 [ 211.365867] ib_create_send_mad+0xa01/0x11b0 [ 211.365887] ib_umad_write+0x853/0x1c80 Fixes: 2be8e3e ("IB/umad: Add P_Key index support") Signed-off-by: YunJe Shin <ioerts@kookmin.ac.kr> Link: https://patch.msgid.link/20260203100628.1215408-1-ioerts@kookmin.ac.kr Signed-off-by: Leon Romanovsky <leon@kernel.org> (cherry picked from commit 5551b02) Signed-off-by: CIQ Kernel Automation <ciq_kernel_automation@ciq.com>
jira VULN-182364 cve CVE-2026-31532 commit-author Samuel Page <sam@bynar.io> commit a535a92 raw_release() unregisters raw CAN receive filters via can_rx_unregister(), but receiver deletion is deferred with call_rcu(). This leaves a window where raw_rcv() may still be running in an RCU read-side critical section after raw_release() frees ro->uniq, leading to a use-after-free of the percpu uniq storage. Move free_percpu(ro->uniq) out of raw_release() and into a raw-specific socket destructor. can_rx_unregister() takes an extra reference to the socket and only drops it from the RCU callback, so freeing uniq from sk_destruct ensures the percpu area is not released until the relevant callbacks have drained. Fixes: 514ac99 ("can: fix multiple delivery of a single CAN frame for overlapping CAN filters") Cc: stable@vger.kernel.org # v4.1+ Assisted-by: Bynario AI Signed-off-by: Samuel Page <sam@bynar.io> Link: https://patch.msgid.link/26ec626d-cae7-4418-9782-7198864d070c@bynar.io Acked-by: Oliver Hartkopp <socketcan@hartkopp.net> [mkl: applied manually] Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> (cherry picked from commit a535a92) Signed-off-by: CIQ Kernel Automation <ciq_kernel_automation@ciq.com>
