UpdatedIn the Linux kernel, the following vulnerability has been resolved: usb: xhci: Check endpoint is valid before dereferencing it When the host controller is not responding, all URBs queued to all endpoints need to be killed. This can cause a kernel panic if we dereference an invalid endpoint. Fix this by using xhci_get_virt_ep() helper to find the endpoint and checking if the endpoint is valid be
UpdatedIn the Linux kernel, the following vulnerability has been resolved: nilfs2: fix general protection fault in nilfs_btree_insert() If nilfs2 reads a corrupted disk image and tries to reads a b-tree node block by calling __nilfs_btree_get_block() against an invalid virtual block address, it returns -ENOENT because conversion of the virtual block address to a disk block address fails. However, this
UpdatedIn the Linux kernel, the following vulnerability has been resolved: Add exception protection processing for vd in axi_chan_handle_err function Since there is no protection for vd, a kernel panic will be triggered here in exceptional cases. You can refer to the processing of axi_chan_block_xfer_complete function The triggered kernel panic is as follows: [ 67.848444] Unable to handle kernel N
UpdatedIn the Linux kernel, the following vulnerability has been resolved: xhci: Fix null pointer dereference when host dies Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race and cause null pointer dereference when host suddenly dies. Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through
UpdatedIn the Linux kernel, the following vulnerability has been resolved: btrfs: qgroup: do not warn on record without old_roots populated [BUG] There are some reports from the mailing list that since v6.1 kernel, the WARN_ON() inside btrfs_qgroup_account_extent() gets triggered during rescan: WARNING: CPU: 3 PID: 6424 at fs/btrfs/qgroup.c:2756 btrfs_qgroup_account_extents+0x1ae/0x260 [btrfs] CPU
Updated- CVE-2023-52896: btrfs: fix race between quota rescan and disable leading to NULL pointer deref Unscored
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between quota rescan and disable leading to NULL pointer deref If we have one task trying to start the quota rescan worker while another one is trying to disable quotas, we can end up hitting a race that results in the quota rescan worker doing a NULL pointer dereference. The steps for this are the following: 1)
Updated In the Linux kernel, the following vulnerability has been resolved: io_uring/poll: don't reissue in case of poll race on multishot request A previous commit fixed a poll race that can occur, but it's only applicable for multishot requests. For a multishot request, we can safely ignore a spurious wakeup, as we never leave the waitqueue to begin with. A blunt reissue of a multishot armed request
UpdatedIn the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_ncm: fix potential NULL ptr deref in ncm_bitrate() In Google internal bug 265639009 we've received an (as yet) unreproducible crash report from an aarch64 GKI 5.10.149-android13 running device. AFAICT the source code is at: https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2022-12-05_13-5.10 The c
UpdatedIn the Linux kernel, the following vulnerability has been resolved: gsmi: fix null-deref in gsmi_get_variable We can get EFI variables without fetching the attribute, so we must allow for that in gsmi. commit 859748255b43 ("efi: pstore: Omit efivars caching EFI varstore access layer") added a new get_variable call with attr=NULL, which triggers panic in gsmi.
UpdatedIn phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification.
UpdatedA vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.5), SIMATIC Energy Manager PRO (All versions < V7.5), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMIT V10 (All versions), SIMIT V11 (All versions < V11.1). Unified Automation .NET based OPC UA Server SDK before 3.2.2 used in Siemens products are affected by a similar vulnerabil
UpdatedNTFS-3G before 75dcdc2 has a use-after-free in ntfs_uppercase_mbs in libntfs-3g/unistr.c. NOTE: discussion suggests that exploitation would be challenging.
UpdatedIn the Linux kernel, the following vulnerability has been resolved: apparmor: Fix null pointer deref when receiving skb during sock creation The panic below is observed when receiving ICMP packets with secmark set while an ICMP raw socket is being created. SK_CTX(sk)->label is updated in apparmor_socket_post_create(), but the packet is delivered to the socket before that, causing the null pointe
UpdatedIn the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Only free buffer VA that is not NULL In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly called only when the buffer to free exists, there are some instances that didn't do the check and triggered warnings in practice. We believe those checks were forgotten unintentionally. Add the chec
