CVE-2026-58384 [HIGH] CWE-190 CVE-2026-58384: A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an unders A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.

CVE-2022-3787 [HIGH] CWE-285 CVE-2022-3787: A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local u A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a

CVE-2026-48864 [HIGH] CWE-787 CVE-2026-48864: A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-c A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result

CVE-2026-53000 [HIGH] CWE-763 CVE-2026-53000: In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfree_rcu t In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfree_rcu to release ops Florian Westphal says: "Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nf_hook_ops that are used to register the callbacks. However, in v5.14 I added the ability to dump the active n

CVE-2008-4302 [MEDIUM] CWE-667 CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a f fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.

CVE-2026-3260 [HIGH] CWE-770 CVE-2026-3260: A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentiall

CVE-2021-20254 [MEDIUM] CWE-125 CVE-2021-20254: A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those v
