https://notcve.org/view.php?id=CVE-2024-42321
In the Linux kernel, the following vulnerability has been resolved: net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE The following splat is easy to reproduce upstream as well as in -stable kernels. Florian Westphal provided the following commit: d1dab4f71d37 ("net: add and use __skb_get_hash_symmetric_net") but this complementary fix has been also suggested by Willem de Bruijn and it can be easily backported to -stable kernel which consists in using DEBUG_NET_WARN_ON_ONCE instead to silence the following splat given __skb_get_hash() is used by the nftables tracing infrastructure to to identify packets in traces.

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-42319 – mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable()
https://notcve.org/view.php?id=CVE-2024-42319
In the Linux kernel, the following vulnerability has been resolved: mailbox: mtk-cmdq: Move devm_mbox_controller_register() after devm_pm_runtime_enable() When mtk-cmdq unbinds, a WARN_ON message with condition pm_runtime_get_sync() < 0 occurs. According to the call tracei below: cmdq_mbox_shutdown mbox_free_channel mbox_controller_unregister __devm_mbox_controller_unregister ... The root cause can be deduced to be calling pm_runtime_get_sync() after calling pm_runtime_disable() as observed below: 1. CMDQ driver uses devm_mbox_controller_register() in cmdq_probe() to bind the cmdq device to the mbox_controller, so devm_mbox_controller_unregister() will automatically unregister the device bound to the mailbox controller when the device-managed resource is removed. That means devm_mbox_controller_unregister() and cmdq_mbox_shoutdown() will be called after cmdq_remove(). 2. CMDQ driver also uses devm_pm_runtime_enable() in cmdq_probe() after devm_mbox_controller_register(), so that devm_pm_runtime_disable() will be called after cmdq_remove(), but before devm_mbox_controller_unregister(). To fix this problem, cmdq_probe() needs to move devm_mbox_controller_register() after devm_pm_runtime_enable() to make devm_pm_runtime_disable() be called after devm_mbox_controller_unregister(). • https://git.kernel.org/stable/c/623a6143a845bd485b00ba684f0ccef11835edab https://git.kernel.org/stable/c/11fa625b45faf0649118b9deaf2d31c86ac41911 https://git.kernel.org/stable/c/a8bd68e4329f9a0ad1b878733e0f80be6a971649 •

In the Linux kernel, the following vulnerability has been resolved: exfat: fix potential deadlock on __exfat_get_dentry_set When accessing a file with more entries than ES_MAX_ENTRY_NUM, the bh-array is allocated in __exfat_get_entry_set.

In the Linux kernel, the following vulnerability has been resolved: media: venus: fix use after free in vdec_close There appears to be a possible use after free with vdec_close(). The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst. Fix it by cancelling the work in vdec_close. • https://git.kernel.org/stable/c/af2c3834c8ca7cc65d15592ac671933df8848115 https://git.kernel.org/stable/c/ad8cf035baf29467158e0550c7a42b7bb43d1db6 https://git.kernel.org/stable/c/72aff311194c8ceda934f24fd6f250b8827d7567 https://git.kernel.org/stable/c/4c9d235630d35db762b85a4149bbb0be9d504c36 https://git.kernel.org/stable/c/f8e9a63b982a8345470c225679af4ba86e4a7282 https://git.kernel.org/stable/c/da55685247f409bf7f976cc66ba2104df75d8dad https://git.kernel.org/stable/c/66fa52edd32cdbb675f0803b3c4da10ea19b6635 https://git.kernel.org/stable/c/6a96041659e834dc0b172dda4b2df512d •
