21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry Pi power driver suffer of firmware property timeouts. The reason is that the IRQ of the underlying BCM2835 mailbox is disabled and rpi_firmware_property_list() will always run into a timeout [1]. Since the VideoCore side isn't consider as a wakeup source, set the IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled during suspend-resum... • https://git.kernel.org/stable/c/0bae6af6d704f026d4938739786e0a69d50177ca •

CVE-2024-49960 – ext4: fix timer use-after-free on failed mount

21 Oct 2024 — 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 We should guarantee the timer is no longer active before kfree(sbi).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_handl... • https://git.kernel.org/stable/c/cf3196e5e2f36cd80dab91ffae402e13935724bc •
CVE-2024-49959 – jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error
