2024-02-27 CVE-2021-46945 In the Linux kernel, the following vulnerability has been resolved: ext4: always panic when errors=panic is specified Before commit 014c9caa29d3 ("ext4: make ext4_abort() use __ext4_error()"), the following series of commands would trigger a panic: 1. mount /dev/sda -o ro,errors=panic test 2. mount /dev/sda -o remount,abort test After commit 014c9caa29d3, remounting a file system using the test mount option "abort" will no longer trigger a panic. This commit will restore the behaviour... Linux_kernel 5.5
2024-02-27 CVE-2021-46947 In the Linux kernel, the following vulnerability has been resolved: sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues efx->xdp_tx_queue_count is initially initialized to num_possible_cpus() and is later used to allocate and traverse efx->xdp_tx_queues lookup array. However, we may end up not initializing all the array slots with real queues during probing. This results, for example, in a NULL pointer dereference, when running "# ethtool -S <iface>", similar to... Linux_kernel 5.5
2024-02-27 CVE-2021-46948 In the Linux kernel, the following vulnerability has been resolved: sfc: farch: fix TX queue lookup in TX event handling We're starting from a TXQ label, not a TXQ type, so efx_channel_get_tx_queue() is inappropriate (and could return NULL, leading to panics). Linux_kernel 5.5
2024-02-27 CVE-2021-46949 In the Linux kernel, the following vulnerability has been resolved: sfc: farch: fix TX queue lookup in TX flush done handling We're starting from a TXQ instance number ('qid'), not a TXQ type, so efx_get_tx_queue() is inappropriate (and could return NULL, leading to panics). Linux_kernel 5.5
2024-02-27 CVE-2021-46950 In the Linux kernel, the following vulnerability has been resolved: md/raid1: properly indicate failure when ending a failed write request This patch addresses a data corruption bug in raid1 arrays using bitmaps. Without this fix, the bitmap bits for the failed I/O end up being cleared. Since we are in the failure leg of raid1_end_write_request, the request either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded). Linux_kernel 7.8
2024-02-27 CVE-2021-46951 In the Linux kernel, the following vulnerability has been resolved: tpm: efi: Use local variable for calculating final log size When tpm_read_log_efi is called multiple times, which happens when one loads and unloads a TPM2 driver multiple times, then the global variable efi_tpm_final_log_size will at some point become a negative number due to the subtraction of final_events_preboot_size occurring each time. Use a local variable to avoid this integer underflow. The following issue is now... Linux_kernel 5.5
2024-02-27 CVE-2021-46952 In the Linux kernel, the following vulnerability has been resolved: NFS: fs_context: validate UDP retrans to prevent shift out-of-bounds Fix shift out-of-bounds in xprt_calc_majortimeo(). This is caused by a garbage timeout (retrans) mount option being passed to nfs mount, in this case from syzkaller. If the protocol is XPRT_TRANSPORT_UDP, then 'retrans' is a shift value for a 64-bit long integer, so 'retrans' cannot be >= 64. If it is >= 64, fail the mount and return an error. Linux_kernel 7.1
2024-02-27 CVE-2021-46953 In the Linux kernel, the following vulnerability has been resolved: ACPI: GTDT: Don't corrupt interrupt mappings on watchdow probe failure When failing the driver probe because of invalid firmware properties, the GTDT driver unmaps the interrupt that it mapped earlier. However, it never checks whether the mapping of the interrupt actially succeeded. Even more, should the firmware report an illegal interrupt number that overlaps with the GIC SGI range, this can result in an IPI being... Linux_kernel 6.7
2024-02-27 CVE-2021-46954 In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_frag: fix stack OOB read while fragmenting IPv4 packets when 'act_mirred' tries to fragment IPv4 packets that had been previously re-assembled using 'act_ct', splats like the following can be observed on kernels built with KASAN: BUG: KASAN: stack-out-of-bounds in ip_do_fragment+0x1b03/0x1f60 Read of size 1 at addr ffff888147009574 by task ping/947 CPU: 0 PID: 947 Comm: ping Not tainted 5.12.0-rc6+...

2024-02-27 CVE-2021-46911 In the Linux kernel, the following vulnerability has been resolved: ch_ktls: Fix kernel panic Taking page refcount is not ideal and causes kernel panic sometimes. It's better to take tx_ctx lock for the complete skb transmit, to avoid page cleanup if ACK received in middle. Linux_kernel 5.5
