Linux Kernel Missing Initialization of a Variable Vulnerability
Linux Kernel is listed in CISA's Known Exploited Vulnerabilities catalog (CVE-2026-46300). Linux Kernel contains a missing initialization of a variable vulnerability that could allow for unintended modification of page-cache-backed data via failure to preserve the shared-fragment marker during socket buffer coalescing, causing ESP input processing to decrypt shared fragments in place. This vulnerability can be chained with CVE-2026-109618 and CVE-2026-109619 to implant PHP webshells and run commands as root. CISA remediation due date: 2026-10-31. If you need help checking exposure, call (864) 335-9223.
Linux Kernel Out-of-Bounds Write Vulnerability
Linux Kernel is listed in CISA's Known Exploited Vulnerabilities catalog (CVE-2026-53266). Linux Kernel contains an out-of-bounds write vulnerability in the ebtables SNAT target which allows an ARP sender hardware address rewrite to write directly into a nonlinear socket-buffer fragment backed by a splice-imported file page. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version. CISA remediation due date: 2026-09-21. If you need help checking exposure, call (864) 335-9223.
Linux Kernel Race Condition Vulnerability
Linux Kernel is listed in CISA's Known Exploited Vulnerabilities catalog (CVE-2025-39964). Linux Kernel contains a race condition vulnerability which allows concurrent writes to the same AF_ALG socket causing data to be unpredictably interleaved and creating inconsistencies in the socket's internal state. CISA remediation due date: 2026-09-21. If you need help checking exposure, call (864) 335-9223.
Linux Kernel Improper Check for Unusual or Exceptional Conditions Vulnerability
Linux Kernel is listed in CISA's Known Exploited Vulnerabilities catalog (CVE-2025-39682). Linux Kernel contains an improper check for unusual or exceptional conditions vulnerability in the TLS receive path which allows a zero-length record retrieved from the rx_list to bypass the intended recvmsg() record-type handling, potentially causing subsequent TLS records to be processed using incorrect zero-copy and queuing assumptions. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version. CISA remediation due date: 2026-09-21. If you need help checking exposure, call (864) 335-9223.
