https://notcve.org/view.php?id=CVE-2025-37998
29 May 2025 — In the Linux kernel, the following vulnerability has been resolved: openvswitch: Fix unsafe attribute parsing in output_userspace() This patch replaces the manual Netlink attribute iteration in output_userspace() with nla_for_each_nested(), which ensures that only well-formed attributes are processed. • https://git.kernel.org/stable/c/ccb1352e76cff0524e7ccb2074826a092dd13016 •

CVE-2025-37995 – module: ensure that kobject_put() is safe for module type kobjects
https://notcve.org/view.php?id=CVE-2025-37995
29 May 2025 — In the Linux kernel, the following vulnerability has been resolved: module: ensure that kobject_put() is safe for module type kobjects In 'lookup_or_create_module_kobject()', an internal kobject is created using 'module_ktype'. So call to 'kobject_put()' on error handling path causes an attempt to use an uninitialized completion pointer in 'module_kobject_release()'. In this scenario, we just want to release kobject without an extra synchronization required for a regular module unloading process, so adding ... • https://git.kernel.org/stable/c/942e443127e928a5631c3d5102aca8c8b3c2dd98 •

CVE-2025-37992 – net_sched: Flush gso_skb list too during ->change()
https://notcve.org/view.php?id=CVE-2025-37992
26 May 2025 — In the Linux kernel, the following vulnerability has been resolved: net_sched: Flush gso_skb list too during ->change() Previously, when reducing a qdisc's limit via the ->change() operation, only the main skb queue was trimmed, potentially leaving packets in the gso_skb list. This could result in NULL pointer dereference when we only check sch->limit against sch->q.qlen. This patch introduces a new helper, qdisc_dequeue_internal(), which ensures both the gso_skb list and the main queue are properly flushed... • https://git.kernel.org/stable/c/76e3cc126bb223013a6b9a0e2a51238d1ef2e409 •

CVE-2025-37991 – parisc: Fix double SIGFPE crash
https://notcve.org/view.php?id=CVE-2025-37991
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: parisc: Fix double SIGFPE crash Camm noticed that on parisc a SIGFPE exception will crash an application with a second SIGFPE in the signal handler. Dave analyzed it, and it happens because glibc uses a double-word floating-point store to atomically update function descriptors. As a result of lazy binding, we hit a floating-point store in fpe_func almost immediately. When the T bit is set, an assist exception trap occurs when when the co-pr... • https://git.kernel.org/stable/c/ec4584495868bd465fe60a3f771915c0e7ce7951 •

CVE-2025-37990 – wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage()

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage() The function brcmf_usb_dl_writeimage() calls the function brcmf_usb_dl_cmd() but dose not check its return value. The 'state.state' and the 'state.bytes' are uninitialized if the function brcmf_usb_dl_cmd() fails. It is dangerous to use uninitialized variables in the conditions.

CVE-2025-37984 – crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP()
https://notcve.org/view.php?id=CVE-2025-37984
20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: crypto: ecdsa - Harden against integer overflows in DIV_ROUND_UP() Herbert notes that DIV_ROUND_UP() may overflow unnecessarily if an ecdsa implementation's ->key_size() callback returns an unusually large value. Herbert instead suggests (for a division by 8): X / 8 + !!(X & 7) Based on this formula, introduce a generic DIV_ROUND_UP_POW2() macro and use it in lieu of DIV_ROUND_UP() for ->key_size() return values. Additionally, use the macro... • https://git.kernel.org/stable/c/921b8167f10708e38080f84e195cdc68a7a561f1 •

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: block: fix resource leak in blk_register_queue() error path When registering a queue fails after blk_mq_sysfs_register() is successful but the function later encounters an error, we need to clean up the blk_mq_sysfs resources.

20 May 2025 — In the Linux kernel, the following vulnerability has been resolved: iio: light: opt3001: fix deadlock due to concurrent flag access The threaded IRQ function in this driver is reading the flag twice: once to lock a mutex and once to unlock it. Even though the code setting the flag is designed to prevent it, there are subtle cases where the flag could be true at the mutex_lock stage and false at the mutex_unlock stage. This results in the mutex not being unlocked, resulting in a deadlock. Fix it by making th... • https://git.kernel.org/stable/c/94a9b7b1809f56cfaa080e70ec49b6979563a237 •
