postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-49417

Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-accessible by default. On a system wit...

CVE-2026-45258 Multiple vulnerabilities in the sound(4) mmap path

dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narrowed from 64 to 32 bits when converted to ...

EUVD-2026-39776

When used to deliver a signal to a specific thread, thrkill22 called pcansignal to determine whether the operation was permitted but did not check the result before delivering the signal. The signal was sent even when the permission check failed. The system call returned the resulting error to th...

CVE-2026-52995

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS subsystem. This vulnerability allows a local unprivileged user to disclose sensitive kernel memory. When a user queries connection information through getsockoptSOLRDS, RDSINFOIBCONNECTIONS while an RDS connection is not fully...

CVE-2026-45257 Arbitrary file overwrite via the KTLS receive path

The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through non-anonymous MEXTPG pages or...

CVE-2026-45256

CVE-2026-45256 affects FreeBSD thr_kill2(2). The kernel failed to verify the result of p_cansignal() before delivering a signal, allowing unprivileged local users who know target PIDs to signal processes they normally could not, including root-owned ones. This can lead to stopping or terminating ...

CVE-2026-52941

A flaw was found in the Linux kernel's net/smc module. An unprivileged local user could trigger a null pointer dereference by performing sendmsg or recvmsg operations on an SMC-D Shared Memory Communications - Direct socket while the smcmsgevent tracepoint is enabled. This can lead to a general...

CVE-2026-52940

A flaw was found in the Linux kernel's tun driver. An unprivileged user can exploit this vulnerability by setting the virtual network vnet header size to 24 bytes. This action causes the kernel to copy partially initialized stack memory to userspace when reading non-tunnel packets, leading to the...

CVE-2026-7574

Anthropic Claude Desktop Cowork VM images (v1.1348.0–v1.2278.0) do not validate the contents of rootfs.img at time-of-use; only file presence and a version marker are checked. A local, unprivileged macOS user can modify the VM root filesystem image and have it trusted on subsequent Cowork VM boot...

CVE-2026-12602 Incorrect permissions in ArubaSign by Aruba

Incorrect default permissions in ArubaSign, affecting versions prior to v4.6.6. The vulnerability is caused by the assignment of inappropriate permissions during the software’s default installation, whereby the main executable and other programme files located in C:\Program Files have excessive...

Astra Linux – Vulnerability in OpenSSH

In OpenSSH 8.2, the scp client incorrectly sends duplicate responses to the server when a utimes system call fails. This allows a malicious, unprivileged user on the remote server to overwrite arbitrary files in the client’s download directory by creating a crafted subdirectory anywhere on the...
