CVE-2026-78322 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 6.5 Medium
A flaw was found in file-roller. When opening or extracting a malicious 7z or RAR archive containing a file entry with an excessively long path, file-roller's progress-line parsing copies the path into a fixed-size stack buffer using an unbounded string copy. This can trigger a stack buffer overflow and cause file-roller to terminate, resulting in a denial of service. To exploit this flaw, a victim must open or extract the crafted archive using file-roller.
CVE-2026-77159 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Els 2026-11-06 5.5 Medium
A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost() function. The function uses a path-based chown() on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd (running as root) to transfer ownership of an arbitrary file to the swtpm user.
CVE-2026-77014 1 Redhat 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more 2026-11-06 5.3 Medium
A flaw was found in libsoup's SoupServer HTTP Range header processing. The sort_ranges() comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INT_MAX. This causes silent omission of requested byte ranges from HTTP 206 Partial Content responses on resources larger than approximately 2 GB.
CVE-2026-76925 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-06 5.8 Medium
A flaw was found in Flatpak. A Time-of-check to time-of-use (TOCTOU) race condition exists in the `org.freedesktop.Flatpak.SystemHelper` component. This vulnerability occurs because a privileged `chmod` operation executes before the OSTree repository validation within the `Deploy()` function. An attacker can exploit this timing window to redirect symlinks to arbitrary files, potentially leading to unauthorized file manipulation or information disclosure.
CVE-2026-76781 1 Redhat 7 Enterprise Linux, Hardened Images, Hummingbird and 4 more 2026-11-06 5.5 Medium
A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS).
CVE-2026-75883 2 Ppp Project, Redhat 3 Ppp, Enterprise Linux, Rhel Els 2026-11-06 6.8 Medium
A flaw was found in pppd. A remote attacker could exploit a buffer overflow vulnerability in the PEAP response handling. By sending a specially crafted PEAP Request packet, an attacker could cause the pppd process to corrupt global static data, leading to incorrect behavior or a system crash.
CVE-2026-73196 2 Freeipa, Redhat 3 Freeipa, Enterprise Linux, Rhel Els 2026-11-05 4.3 Medium
A flaw was found in FreeIPA. A low-privilege authenticated user can exploit this vulnerability by submitting an oversized One-Time Password (OTP) key value. This oversized key is then decoded and re-encoded without proper size limits, consuming excessive CPU and memory resources. This can lead to a denial of service, degrading the availability of the IPA service.
CVE-2026-66339 3 Gnome, Libsoup, Redhat 4 Libsoup, Libsoup, Enterprise Linux and 1 more 2026-11-05 6.5 Medium
A flaw was found in libsoup. After a CONNECT tunnel is established through an HTTP proxy, libsoup incorrectly attaches the Proxy-Authorization header to subsequent HTTPS requests sent through that tunnel to the destination server. This allows the destination server to capture proxy credentials, leading to information disclosure.
CVE-2026-73585 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-05 6.3 Medium
A flaw was found in sblim-cmpi-base. Insecure temporary file creation in the provider registration scripts allows a local unprivileged user to perform a symlink attack. By creating a symlink in a world-writable directory, an attacker can redirect privileged writes to an arbitrary file during script execution in a privileged context. This can lead to the overwrite of root-owned files, potentially disrupting system services or operation. Exploitation is conditional on the script running with elevated privileges and may be mitigated by sticky-directory symlink protections.
CVE-2026-73584 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-05 6.3 Medium
A flaw was found in sblim-sfcb. A local, low-privileged attacker can exploit a race condition during privileged instance migration by manipulating a temporary file in the `/tmp` directory. By repeatedly recreating a symbolic link, the attacker can redirect privileged output to an arbitrary file. This can lead to privileged file corruption or a denial of service (DoS) on the system.
CVE-2026-73583 1 Redhat 2 Enterprise Linux, Rhel Els 2026-11-05 6.6 Medium
A flaw was found in sblim-sfcb. A local attacker with access to the system can exploit an unsafe deserialization vulnerability in the provider-manager's inter-process communication (IPC) message parsing. By sending a specially crafted message, the attacker can cause out-of-bounds memory access, leading to the termination of the provider-manager process and a denial of service. This could also potentially result in limited unintended information disclosure.
CVE-2026-71224 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 4.7 Medium
A stack overflow vulnerability was found in gfs2-utils. The metadata walk code in metawalk.c uses alloca() with an untrusted inode height value from on-disk metadata without bounds validation, causing stack exhaustion and a denial of service when processing crafted GFS2 filesystem images.
CVE-2026-71222 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 5.3 Medium
A heap out-of-bounds read vulnerability was found in gfs2-utils. The ea_num_ptrs field from on-disk extended attribute metadata is consumed without bounds validation, causing a heap buffer over-read that may disclose sensitive memory contents or cause a crash when processing crafted GFS2 filesystem images.
CVE-2026-71221 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 7 High
A stack out-of-bounds write vulnerability was found in gfs2-utils. In savemeta, the height value from on-disk inode metadata is used as a loop bound without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem images.
CVE-2026-71220 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 7 High
A stack out-of-bounds write vulnerability was found in gfs2-utils. In gfs2_edit, the di_height field from on-disk inode metadata is used as an array index without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem images.
CVE-2026-71219 1 Redhat 3 Enterprise Linux, Gfs2-utils, Rhel Els 2026-11-05 4.7 Medium
A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca() with an exponentially-derived size from the untrusted on-disk di_depth field without bounds validation. A crafted GFS2 filesystem image with a large di_depth value causes stack exhaustion and a denial of service when processed by fsck.gfs2, gfs2_edit, or savemeta.
CVE-2026-71218 2 Iperf3 Project, Redhat 3 Iperf3, Enterprise Linux, Rhel Els 2026-11-05 5.3 Medium
A flaw was found in iperf3. A remote unauthenticated attacker can exploit a vulnerability in the `JSON_read()` function, which accepts a peer-controlled message length and allocates memory without an upper bound. This allows the attacker to trigger excessive memory consumption, leading to a Denial of Service (DoS) through memory exhaustion, severe slowdown, or termination of the iperf3 service.
CVE-2026-70368 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Els, Stunnel 2026-11-05 6.5 Medium
A stack-based out-of-bounds read vulnerability exists in the "s_vlog" function of stunnel, when handling oversized log messages via "vsnprintf". A remote attacker with network access to a stunnel service can send protocol inputs that trigger a log message longer than 1024 bytes, leading to an out-of-bounds stack read and a potential crash. In certain corner cases, the same vulnerability could be used to replace a series of trailing "\n" characters with "\0".
CVE-2026-70367 2 Redhat, Stunnel 3 Enterprise Linux, Rhel Els, Stunnel 2026-11-05 5.4 Medium
A Server-Side Request Forgery (SSRF) bypass vulnerability exists in “stunnel” 5.79 and lower when configured in SOCKS proxy mode. This flaw allows a client to bypass intended localhost restrictions by using IPv4-mapped IPv6 addresses (e.g., “::ffff:127.0.0.1”) or unspecified addresses ("0.0.0.0", "::"), enabling access to loopback-only services on the "stunnel" host that should not be network-reachable.
CVE-2026-68742 3 Fedoraproject, Redhat, Sssd 6 Sssd, Enterprise Linux, Openshift and 3 more 2026-11-05 5.5 Medium
A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
