In the Linux kernel, the following vulnerability has been resolved:

mptcp: ensure snd_una is properly initialized on connect

This is strictly related to commit fb7a0d334894 ("mptcp: ensure snd_nxt is properly initialized on connect"). It turns out that syzkaller can trigger the retransmit after fallback and before processing any other incoming packet - so that snd_una is still left uninitialized.

Address the issue explicitly initializing snd_una together with snd_nxt and write_seq.

nfsd: NULL dereference in nfs3svc_encode_getaclres. scsi: core: use-after-free vulnerability. NFSD: vulnerability caused by loff_t overflow on the server when a client reads near the maximum offset, causing the server to return an EINVAL error, which the client retries indefinitely, instead of handling out-of-range READ requests by returning a short result with an EOF flag. NFSD: Vulnerability caused by an underflow in ia_size due to a mismatch between signed and unsigned 64-bit file size values, which can cause issues when handling large file sizes from NFS clients. NFSD: Vulnerability handling large file sizes for NFSv3 improperly capping client size values larger than s64_max, leading to unexpected behavior and potential data corruption. sh: cpuinfo: warning for CONFIG_CPUMASK_OFFSTACK. When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning when showing /proc/cpuinfo. A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables.
