CVE-2024-38635 – soundwire: cadence: fix invalid PDI offset
https://notcve.org/view.php?id=CVE-2024-38635
21 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: soundwire: cadence: fix invalid PDI offset For some reason, we add an offset to the PDI, presumably to skip the PDI0 and PDI1 which are reserved for BPT. This code is however completely wrong and leads to an out-of-bounds access. We were just lucky so far since we used only a couple of PDIs and remained within the PDI array bounds. A Fixes: tag is not provided since there are no known platforms where the out-of-bounds would be accessed, and... • https://git.kernel.org/stable/c/002364b2d594a9afc0385c09e00994c510b1d089 • CWE-125: Out-of-bounds Read •
CVE-2024-38634 – serial: max3100: Lock port->lock when calling uart_handle_cts_change()

21 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: vfio/pci: fix potential memory leak in vfio_intx_enable() If vfio_irq_ctx_alloc() failed will lead to 'name' memory leak. Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-confusion error.

CVE-2024-38630 – watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger

21 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger When the cpu5wdt module is removing, the origin code uses del_timer() to de-activate the timer. If the timer handler is running, del_timer() could not stop it and will return directly. If the port region is released by release_region() and then the timer handler cpu5wdt_trigger() calls outb() to write into the region that is released, the use-after-free bug will happen.

CVE-2024-38621 – media: stk1160: fix bounds checking in stk1160_copy_video()
https://notcve.org/view.php?id=CVE-2024-38621
21 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: media: stk1160: fix bounds checking in stk1160_copy_video() The subtract in this condition is reversed. The ->length is the length of the buffer. The ->bytesused is how many bytes we have copied thus far. When the condition is reversed that means the result of the subtraction is always negative but since it's unsigned then the result is a very high positive value. That means the overflow check is never true. • https://git.kernel.org/stable/c/9cb2173e6ea8f2948bd1367c93083a2500fcf08f •
