Affected: Alpaquita:23: linux-lts, Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

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

wifi: mac80211: do not pass a stopped vif to the driver in .get_txpower

Avoid potentially crashing in the driver because of uninitialized private data

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.

The default behavior when the stack-protector detects an overflow is to terminate your application, resulting…

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: Fix driver shutdown on closed serdev The driver shutdown callback (which sends EDL_SOC_RESET to the device over serdev) should not be invoked when HCI device is not open (e.g. if hci_dev_open_sync() failed), because the serdev and its TTY are not open either. Also skip this step if device is powered off (qca_power_shutdown()). The shutdown callback causes use-after-free during system reboot with Qualcomm Atheros Bluetooth: Unable to handle kernel paging request at virtual address 0072662f67726fd7 ...
