CVE-2024-36931 – s390/cio: Ensure the copied buf is NUL terminated
https://notcve.org/view.php?id=CVE-2024-36931
30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: s390/cio: Ensure the copied buf is NUL terminated Currently, we allocate a lbuf-sized kernel buffer and copy lbuf from userspace to that buffer. Later, we use scanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using scanf. Fix this issue by using memdup_user_nul instead. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: s390/cio: asegúrese de que el buf co... • https://git.kernel.org/stable/c/a4f17cc726712a52122ad38540bc3ff3a052d1a4 •
CVE-2024-36930 – spi: fix null pointer dereference within spi_sync

30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: spi: fix null pointer dereference within spi_sync If spi_sync() is called with the non-empty queue and the same spi_message is then reused, the complete callback for the message remains set while the context is cleared, leading to a null pointer dereference when the callback is invoked from spi_finalize_current_message(). With function inlining disabled, the call stack might look like this: _raw_spin_lock_irqsave from complete_with_fl... • https://git.kernel.org/stable/c/ae7d2346dc89ae89a6e0aabe6037591a11e593c0 • CWE-476: NULL Pointer Dereference •

CVE-2024-36927 – ipv4: Fix uninit-value access in __ip_make_skb()
https://notcve.org/view.php?id=CVE-2024-36927
30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix uninit-value access in __ip_make_skb() KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb() tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL while __ip_make_skb() is running, the function will access icmphdr in the skb even if it is not included. This causes the issue reported by KMSAN.

CVE-2024-36923 – fs/9p: fix uninitialized values during inode evict

30 May 2024 — In the Linux kernel, the following vulnerability has been resolved: fs/9p: fix uninitialized values during inode evict If an iget fails due to not being able to retrieve information from the server then the inode structure is only partially initialized. When the inode gets evicted, references to uninitialized structures (like fscache cookies) were being made. This patch checks for a bad_inode before doing anything other than clearing the inode from the cache. Since the inode is bad, it shouldn't have a... • https://git.kernel.org/stable/c/18cf7026355187b8d2b4cdfed61dbf873e9d29ff •
