kernel: dm log: fix out-of-bounds write due to region_count overflow
A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...
kernel: gfs2: Fix use-after-free in iomap inline data write path
A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
kernel: ipc: limit next_id allocation to the valid ID range
A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

util-linux: util-linux: restricted bind mounts do not pin the source, allowing X-mount.owner/group/mode redirection
A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount8 to bind another host directory. If the fst...
util-linux: util-linux: nsenter --join-cgroup leaks root cgroup migration authority
The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve. Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an...
util-linux: util-linux: failed external mount helper still runs privileged X-mount post-hooks
When an external mount. helper runs but exits with a nonzero status, libmount still treats the helper invocation as successful and runs privileged post-mount hooks. A local unprivileged user with an /etc/fstab entry that uses the user option together with X-mount.idmap or X-mount.owner/group/mode...
util-linux: util-linux: X-mount.subdir detached-tree resolution can escape via intermediate symlinks
The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

An attacker could exploit this to bypass certificate validation, allowing ...
crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building
A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...
net/mail: golang: net/mail: Denial of Service via pathological email address parsing
A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...
net/url: Incorrect parsing of IPv6 host literals in net/url
The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...
net/mail: golang: Go net/mail: Denial of Service via crafted email inputs
A flaw was found in the net/mail package of the Go programming language. An attacker could provide specially crafted inputs to the ParseAddress, ParseAddressList, or ParseDate functions.

curl: libcurl: Information disclosure via improper Public Suffix List boundary check
A flaw was found in libcurl when libpsl support is enabled. A remote attacker could exploit this vulnerability by setting a Set-Cookie header with a Domain attribute that explicitly matches a public suffix. This improper handling causes libcurl to save the cookie with a wildcard domain scope,...
curl: libcurl: Information disclosure via incorrect connection reuse with Negotiate authentication
A flaw was found in libcurl. This vulnerability allows an attacker to reuse an HTTP connection set up for a given hostname using Negotiate authentication. When an initial request is made with empty credentials, a subsequent user's request can be sent over a previously authenticated connection...
curl: curl: Authentication bypass in OpenLDAP SASL negotiation via Man-in-the-Middle (MITM) attack
A flaw was found in libcurl's SASL Simple Authentication and Security Layer negotiation for LDAP Lightweight Directory Access Protocol authentication when using the OpenLDAP backend. An incomplete handshake sequence can be misinterpreted as a successful cryptographic verification. A remote...
curl: libcurl: Use-after-free in HTTP/2 Server Push with shared connections
A flaw was found in libcurl. When libcurl handles HTTP/2 Server Push streams and the parent handle shares connections, a use-after-free vulnerability can occur during the cleanup process. This could lead to application crashes, resulting in a denial of service...
curl: curl: Information disclosure due to secure cookie attribute bypass
A flaw was found in curl. When a Set-Cookie: header uses a tab character instead of a space before the Secure attribute, curl incorrectly stores the cookie without the Secure flag. This can lead to information disclosure, as the cookie may then be sent over unencrypted HTTP connections to the sam...
curl: curl: Public key pinning bypass allows unauthenticated connections
A flaw was found in libcurl, a client-side URL transfer library. When public key pinning is configured, but standard peer verification is explicitly disabled, libcurl incorrectly allows connections to proceed without enforcing the public key pinning. This bypass enables unauthenticated connection...
