Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-63832
High

In the Linux kernel, the mt76 driver lacks a check whether the WCID (Wireless Client ID) has already been published before reinitializing the poll_list. This causes corruption of the dev->sta_poll_list structure, potentially leading to system crashes.

CVE-2026-63831
High

In the Linux kernel's mac802154 subsystem, a vulnerability was found due to missing skb_cow_data() calls before in-place cryptographic operations. LLSEC encrypt/decrypt functions modify shared skb data buffers, leading to data corruption, use-after-free, and kernel crashes under concurrent 802.15.4 traffic with security enabled.

CVE-2026-63829
High

Vulnerability in the Linux kernel ip_gre driver allows a user with CAP_NET_ADMIN in one network namespace to modify a GRE tunnel in another namespace where they lack privileges. Missing CAP_NET_ADMIN check in the target namespace.

CVE-2026-63828
High

Vulnerability in the Linux kernel AppArmor module allows bypassing connect mediation by using MSG_FASTOPEN flag in sendmsg(). A profile allowing send but blocking connect can be bypassed.

CVE-2026-63827
High

A use-after-free vulnerability was found in the rawdata deduplication loop of the AppArmor module in the Linux kernel. The issue occurs when an entry on the rawdata_list has a zero reference count and aa_get_profile_loaddata() performs an unsafe kref_get(), leading to a reference to freed memory.

CVE-2026-63824
High

In the Linux kernel, a vulnerability in keyctl_pkey_params_get_2() was found where incorrect output buffer length calculation can cause overflow when a too small buffer is provided. The fix allocates internal output with the size of the maximum cryptographic primitive length.

CVE-2026-63823
High

A use-after-free vulnerability was found in the Linux kernel's key management subsystem. A race condition between request_key() and KEYCTL_INSTANTIATE_IOV can cause use of freed request_key_auth payload memory.

CVE-2026-63819
High

In the Linux kernel F2FS filesystem, a vulnerability was found due to missing sanity checks in f2fs_get_node_folio_ra(). This can trigger a kernel BUG_ON during file truncation when a corrupted node has mismatched inode and nid in its footer.

CVE-2026-63818
High

In the Linux kernel's F2FS filesystem, the orphan inode recovery function trusts the entry_count from the checkpoint block. A corrupted value larger than F2FS_ORPHANS_PER_BLOCK causes an out-of-bounds read and interprets subsequent data as inode numbers, leading to a kernel panic.

CVE-2026-63817
High

In the Linux kernel's F2FS filesystem, is_meta_ino() unconditionally treats F2FS_COMPRESS_INO() as a meta inode even when compress_cache is disabled. This allows creating a fake internal inode with an out-of-range number, bypassing normal validation.

CVE-2026-63816
High

Vulnerability in the Linux kernel F2FS filesystem leads to a use-after-free (UAF) of f2fs_inode_info.atomic_inode during garbage collection. Missing reference counting can result in accessing freed memory.

CVE-2026-63815
High

In the Linux kernel's F2FS filesystem, a vulnerability was found due to missing validation of i_inline_xattr_size for inodes without the FI_INLINE_XATTR flag. An attacker can exploit a crafted filesystem image to set this value arbitrarily, leading to an out-of-bounds read when processing inline directories.

CVE-2026-63814
High

In the Linux kernel F2FS filesystem, a vulnerability was found due to missing validation of ACL entry sizes in f2fs_acl_from_disk(). A malformed ACL can cause an out-of-bounds read, confirmed by a KASAN report.

CVE-2026-63813
High

The Linux kernel reverts commit 9609dd704725 that removed non-uptodate folios from the page cache in move_data_block. The revert fixes kernel panics reported on nearly full f2fs partitions, caused by a race condition that corrupts the LRU list and frees pages with active LRU links.

CVE-2026-63812
High

In the Linux kernel's F2FS filesystem, a vulnerability was found in the __destroy_extent_node() function where setting the FI_NO_EXTENT flag does not reset the largest extent length to zero or update the inode folio, causing stale cached data and triggering a sanity check error.

CVE-2026-63809
High

In the Linux kernel, a bug was found in __cgroup_bpf_run_filter_sysctl() where a temporary buffer allocated by kvzalloc() was freed using kfree() instead of kvfree(). This can cause memory corruption on large allocations.

CVE-2026-63807
High

In the Linux kernel's KVM subsystem for x86, a vulnerability was found where the base GFN of a shadow page is not verified to be within the target memslot before querying the maximum mapping level. This can cause an out-of-bounds read in the lpage_info structure, resulting in a host page fault and potential system instability.

CVE-2026-63806
High

In the Linux kernel KVM component, a vulnerability allows a guest to trigger a kernel panic (BUG_ON) when writing to an ioeventfd with datamatch enabled. The issue occurs when a guest write crosses a page boundary and the second page contains a datamatch-enabled ioeventfd – an unaligned pointer dereference triggers the BUG_ON.

CVE-2026-63805
High

A bug in the Linux kernel's NX crypto driver (nx_crypto_ctx_exit) caused an incorrect argument type to be used. The nx_crypto_ctx_shash_exit function passed a context pointer (nx_crypto_ctx *) instead of a crypto_tfm * pointer, leading to a memory access violation and system crash (oops).

CVE-2026-63804
High

A use-after-free vulnerability was found in the Linux kernel's GFS2 filesystem in the gfs2_qd_dealloc function. During unmount, an RCU callback may access a freed superblock object, leading to potential security issues.
