https://notcve.org/view.php?id=CVE-2021-4454
27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: can: j1939: fix errant WARN_ON_ONCE in j1939_session_deactivate The conclusion "j1939_session_deactivate() should be called with a session ref-count of at least 2" is incorrect. In some concurrent scenarios, j1939_session_deactivate can be called with the session ref-count less than 2. But there is not any problem because it will check the session active state before session putting in j1939_session_deactivate_locked(). Here is the concurre... • https://git.kernel.org/stable/c/7eef18c0479ba5d9f54fba30cd77c233ebca3eb1 •

27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: i2c: npcm: disable interrupt enable bit before devm_request_irq The customer reports that there is a soft lockup issue related to the i2c driver. After checking, the i2c module was doing a tx transfer and the bmc machine reboots in the middle of the i2c transaction, the i2c module keeps the status without being reset. Due to such an i2c module status, the i2c irq handler keeps getting triggered since the i2c irq handler is registered in the... • https://git.kernel.org/stable/c/56a1485b102ed1cd5a4af8e87ed794699fd1cad2 •

27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: efi: Don't map the entire mokvar table to determine its size Currently, when validating the mokvar table, we (re)map the entire table on each iteration of the loop, adding space as we discover new entries. If the table grows over a certain size, this fails due to limitations of early_memmap(), and we get a failure and traceback: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at mm/early_ioremap.c:139 __early_ioremap+0xef/0x220 ... • https://git.kernel.org/stable/c/46c0454ffb78ce9d3355a3cccac86383ea8ddd55 •

27 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: tee: optee: Fix supplicant wait loop OP-TEE supplicant is a user-space daemon and it's possible for it be hung or crashed or killed in the middle of processing an OP-TEE RPC call. It becomes more complicated when there is incorrect shutdown ordering of the supplicant process vs the OP-TEE client application which can eventually lead to system hang-up waiting for the closure of the client application.

CVE-2023-52927 – netfilter: allow exp not to be removed in nf_ct_find_expectation
https://notcve.org/view.php?id=CVE-2023-52927
14 Mar 2025 — In the Linux kernel, the following vulnerability has been resolved: netfilter: allow exp not to be removed in nf_ct_find_expectation Currently nf_conntrack_in() calling nf_ct_find_expectation() will remove the exp from the hash table. However, in some scenario, we expect the exp not to be removed when the created ct will not be confirmed, like in OVS and TC conntrack in the following patches. This patch allows exp not to be removed by setting IPS_CONFIRMED in the status of the tmpl. In the Linux kernel, the... • https://git.kernel.org/stable/c/3fa58a6fbd1e9e5682d09cdafb08fba004cb12ec •
