CVE Vulnerability Catalog

A vulnerability in the os package of the Go standard library allows improper access to the parent directory of an os.Root by opening a filename ending in "../". For example, Root.Open("../") opens the parent directory, bypassing access restrictions.

A use-after-free vulnerability in SEV firmware allows a malicious hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent, potentially leading to loss of integrity.

A vulnerability in the assembly implementation of an internal cryptographic function on the ppc64le architecture leaks a few bits of secret scalars due to the use of a variable-time instruction. Based on how this function is used, the leakage is not sufficient to recover the private key.

A vulnerability in cross-origin redirect handling causes Proxy-Authorization and Proxy-Authenticate headers to persist, potentially leaking sensitive authentication data.

In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.

The RedirectSlashes function in middleware/strip.go is vulnerable to host header injection leading to an open redirect. This is considered lower-severity as it cannot be exploited from browsers or email clients.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware allows a privileged attacker to modify the lock bit, potentially downgrading the firmware and compromising system integrity.

A flaw in shadow-utils fails to properly clear the buffer when a new password is entered twice and the second attempt fails. This leaves the first password in memory, potentially allowing an attacker with sufficient access to retrieve it.

A race condition in the Go database/sql package can overwrite expected results when a query is cancelled during the Scan method call while other queries run in parallel.

A vulnerability in the Nokogiri library affects the `Nokogiri::XML::NodeSet#[]` method (and its alias `#slice`). The index check against the node set's bounds used a 32-bit-truncated copy of the index, allowing a large negative index to pass the check and then be used at full width, reading outside the node set's storage.

In the Linux kernel, in the sc16is7xx serial driver, a TX FIFO corruption was fixed that could occur when a packet was received on channel A at almost the same time as a packet was about to be transmitted on channel B.

In the Linux kernel, in the Btrfs filesystem, an issue with readahead on the relocation inode was fixed when the filesystem uses a RAID stripe tree (RST), which could cause ENOENT errors.

In the Linux kernel, in the L2TP subsystem, a possible tunnel refcount underflow was fixed, which could occur during session deletion when the tunnel pointer was invalid.

A vulnerability in Linux PAM before version 1.6.0 allows attackers to cause a denial of service by blocking the login process. The issue stems from the lack of the O_DIRECTORY flag in the openat call for the protect_dir function, enabling the use of mkfifo.

Decode, DecodeChain, DecodeTrustStore, and ToPEM can incorrectly accept PKCS#12 files which were encoded with the wrong password, due to a failure to reject excessively-short PBMAC1 keys. Users who decode PKCS#12 files from untrusted sources and rely on the password for authentication can be affected.

In the Linux kernel, in the Bluetooth subsystem (MGMT), possible deadlocks were fixed that could occur due to hci_cmd_sync_dequeue, causing threads to block for extended periods.

In the Linux kernel, in the DRM/XE driver (guc_submit), a race condition around the suspend_pending field was fixed, which could cause assertions and warnings in certain test scenarios.

In the Linux kernel, in the Bluetooth subsystem (hci_conn), the function disable_delayed_work_sync is used instead of cancel_delayed_work_sync, which not only cancels ongoing work but also disables new submissions, which is desirable.

In the Linux kernel's F2FS filesystem, there is potential corruption when moving a directory, similar to an issue in ext4. The fix addresses this problem.

In the Linux kernel's fork function, a race condition exists between fork and hugetlbfs file operations. The fix defers linking the file VMA until the VMA is fully initialized.
