In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Validated numaces and hardened the ACE walk in smbinheritdacl. smbinheritdacl relies on the numaces value from the parent directory’s DACL xattr and uses it to allocate memory for the heap: acesbase = kmallocsizeofstruc...

Astra Linux - уязвимость в qemu

A flaw was discovered in the QXL display device emulation in QEMU. An integer overflow in the cursoralloc function can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process...

Astra Linux - уязвимость в qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: smb: server: Fixed a leak in activenumconn when there is a failure in transport allocation. The commit 77ffbcac4e56 “smb: server: fixed the leak of activenumconn in ksmbdtcpnewconnection” addresses the failure path in kthreadrun...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: spi: Fixed a use-after-free issue during controller registration failures. Be sure to also deregister from the driver core in case the per-cpu statistics allocation fails during controller registration, in order to avoid...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/migrate: prevents infinite recursion. If the buf + offset is not aligned to XECAHELINEBYTES, we fall back to using a bounce buffer. However, the bounce buffer is allocated on the stack, and the only alignment requirement...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: Networking: dsa: felix: fixed the possible dereferencing of a NULL pointer. As a possible failure during allocation, kzalloc may return a NULL pointer. Therefore, it is better to check for the value of 'sgi' to prevent the...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: blk-mq: Fixed an issue where IO operations could hang due to a race condition involving the sbitmap wakeup mechanism. In blkmqmarktagwait, addwaitqueue might be re-ordered. In addition, blkmqgetdrivertag might fail if the driver...
