In the Linux kernel, the following vulnerability has been resolved: mm/pageowner: use strscpy instead of strlcpy current-comm is not a string no guarantee for a zero byte in it. strlcpys1, s2, l is calling strlens2, potentially causing out-of-bound access, as reported by syzbot: detected buffer...

kernel: writeback: avoid use-after-free after removing device

In the Linux kernel, the following vulnerability has been resolved: writeback: avoid use-after-free after removing device When a disk is removed, bdiunregister gets called to stop further writeback and wait for associated delayed work to complete. However, wbinodewritebackend may schedule bandwid...

kernel: ipv6: Fix an uninit variable access bug in __ip6_make_skb()

A flaw was identified in the Linux kernel’s IPv6 networking code in the function ip6makeskb. Under certain conditions—such as when using raw IPv6 sockets and processing ICMPv6 headers—the code may access an uninitialized variable because the expected header data is not guaranteed to reside in the...

kernel: net/mlx5: Devcom, fix error flow in mlx5_devcom_register_device

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Devcom, fix error flow in mlx5devcomregisterdevice In case devcom allocation is failed, mlx5 is always freeing the priv. However, this priv might have been allocated by a different thread, and freeing it might lead to...

kernel: net/tunnel: wait until all sk_user_data reader finish before releasing the sock

In the Linux kernel, the following vulnerability has been resolved: net/tunnel: wait until all skuserdata reader finish before releasing the sock There is a race condition in vxlan that when deleting a vxlan device during receiving packets, there is a possibility that the sock is released after...
