In the Linux kernel, the following vulnerability has been resolved: fbcon: Avoid OOB font access if console rotation fails Clear the font buffer if the reallocation during console rotation fails in fbconrotatefont. The putcs implementations for the rotated buffer will return early in this case. S...
CVE-2026-46191
CVE-2026-46191 concerns the Linux kernel fbcon component: when console rotation fails during fbcon_rotate_font(), the font buffer may overflow due to an OOB access. The fix clears the font buffer if the reallocation during console rotation fails and ensures the rotated buffer does not overflow. D...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1 Description An out-of-bounds font access occurs in the fbcon rotate font function when console rotation fails. The system retains the ol...
FreeRDP: FreeRDP: Memory corruption vulnerability allows denial of service or arbitrary code execution
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A memory corruption vulnerability exists in the persistent cache handling. If a memory reallocation fails, an internal size variable is incorrectly updated, while the data pointer still refers to the original,...
SUSE CVE-2026-44070
An unbounded memory reallocation in the charset conversion code in Netatalk 2.0.0 through 4.4.2 allows a remote authenticated attacker to cause a minor denial of service via crafted character conversion requests...
CVE-2026-43497
A flaw was found in the Linux kernel's udlfb driver. This use-after-free vulnerability occurs because the dlfbopsmmap function does not properly track active memory mappings. When the framebuffer is reallocated, existing memory page table entries PTEs are not invalidated. This allows a local...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Set the new vector length before reallocating it. As part of fixing the allocation of the buffer for SVE states when changing the SME vector length, we introduced an immediate reallocation of the SVE state. This...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: bpf, verifier: Fixed a memory leak in array reallocation for stack state. If an error NULL is returned by krealloc, callers of reallocarray would set their allocation pointers to NULL. However, when an error occurs in krealloc, i...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: i40e: Fixed DMA mapping leaks During the reallocation of RX buffers, new DMA mappings are created for those buffers. Reproduction steps: While doing the following: Do For i=0; i=8160; i=i+32 Do ethtool -G enp130s0f0 rx $i tx $...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: Ice: Fixed DMA mapping leaks The leak was fixed when the user changed ring parameters. During the reallocation of RX buffers, new DMA mappings are created for those buffers. New buffers with a different RX ring count should...
Astra Linux – Vulnerability in Linux, Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: regmap: A possible double-free condition in regcacherbtreeexit has been fixed. In regcacherbtreeinserttoblock, when realloc fails with the value “present”, the “blk” variable, which is supposed to point to ‘rbnode-block’, will be...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: Issue: Skipping the reallocation of the Unicode buffer when resizing the alternate screen after exiting the alt-screen mode. When the enteraltscreen function saves vcunilines into vcsavedunilines and sets vcunilines to NULL, a...
CVE-2026-41257 jq: Signed-int overflow in `stack_reallocate` (jq VM stack)
jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB via deeply nested generator forks, the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for ...
