    net: missing check virtio

    In the Linux kernel, the following vulnerability has been resolved: net: missing check virtio Two missing check in virtio_net_hdr_to_skb() allowed syzbot to crash kernels again 1. After the skb_segment function the buffer may become non-linear (nr_frags != 0), but since the SKBTX_SHARED_FRAG flag is not set anywhere the __skb_linearize function will not be executed, then the buffer will remain non-linear. Then the condition (offset >= skb_headlen(skb)) becomes true, which causes WARN_ON_ONCE in skb_checksum_help. 2. The struct sk_buff and struct virtio_net_hdr members must be mathematically related. (gso_size) must be greater than (needed

    landlock: Don't lose track of restrictions on cred_transfer

    In the Linux kernel, the following vulnerability has been resolved: landlock: Don't lose track of restrictions on cred_transfer When a process' cred struct is replaced, this _almost_ always invokes the cred_prepare LSM hook; but in one special case (when KEYCTL_SESSION_TO_PARENT updates the parent's credentials), the cred_transfer LSM hook is used instead. Landlock only implements the cred_prepare hook, not cred_transfer, so KEYCTL_SESSION_TO_PARENT causes all information on Landlock restrictions to be lost. This basically means that a process with the ability to use the fork() and keyctl() syscalls can get rid of all Landlock restriction

    media: venus: fix use after free in vdec_close

    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.

    sysctl: always initialize i_uid/i_gid

    In the Linux kernel, the following vulnerability has been resolved: sysctl: always initialize i_uid/i_gid Always initialize i_uid/i_gid inside the sysfs core so set_ownership() can safely skip setting them. Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() was not implemented. It also missed adjusting net_ctl_set_ownership() to use the same default values in case the computation of a better value failed.

    udf: Avoid using corrupted block bitmap buffer

    In the Linux kernel, the following vulnerability has been resolved: udf: Avoid using corrupted block bitmap buffer When the filesystem block bitmap is corrupted, we detect the corruption while loading the bitmap and fail the allocation with error. However the next allocation from the same bitmap will notice the bitmap buffer is already loaded and tries to allocate from the bitmap with mixed results (depending on the exact nature of the bitmap corruption). Fix the problem by using BH_verified bit to indicate whether the bitmap is valid or not.

    PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal

    In the Linux kernel, the following vulnerability has been resolved: PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal Keith reports a use-after-free when a DPC event occurs concurrently to hot-removal of the same portion of the hierarchy: The dpc_handler() awaits readiness of the secondary bus below the Downstream Port where the DPC event occurred. To do so, it polls the config space of the first child device on the secondary bus. If that child device is concurrently removed, accesses to its struct pci_dev cause the kernel to oops. That's because pci_bridge_wait_for_secondary_bus() neglects to hold a reference on the child d

    In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page().

So, modify nilfs_btnode_create_block() and its callers to treat it as a possible filesystem error, rather than triggering a
