  1. CVE-2026-12353 5.3 Moyenne

    Red Hat Certificate System 9 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    An unauthenticated attacker could trigger an Out of Memory condition to crash the Java process for RHCS by repeatedly sending HTTP requests to the TLS endpoint. Depending on how the RHCS server is configured, a manual intervention to restart it may prove necessary.

  2. CVE-2026-65918 7.1 Élevée

    pytorch vision · Linuxfoundation torchvision

    PyTorch torchvision through 0.28.0, fixed in commit 4e05dc2, contains an out-of-bounds heap read vulnerability in the GIF decoder's read_from_tensor callback that passes unclamped length to memcpy. Attackers can supply malicious or truncated GIF files to cause denial of service via segmentation fault or disclose adjacent heap memory contents.

  3. CVE-2026-16768 5.3 Moyenne

    GNOME gdk-pixbuf · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A flaw was found in gdk-pixbuf. When parsing a specially crafted ICO file with pixel values that exceed the defined palette range, an out-of-bounds read can occur due to improper bounds checking against the actual palette size. This vulnerability causes heap bytes to be interpreted as valid palette indices and rendered as RGB pixel values in the output image, allowing an attacker to extract heap content via the generated output, such as a thumbnail.

  4. CVE-2026-11804 5.2 Moyenne

    Tridium Niagara Framework · Tridium Niagara Enterprise Security

    Improper handling of insufficient permissions or privileges vulnerability in Tridium Niagara Framework on Windows, Linux, QNX, Tridium Niagara Enterprise Security on Windows, Linux, QNX allows Privilege Abuse. This issue affects Niagara Framework: before 4.14.6, before 4.15.5; Niagara Enterprise Security: before 4.14.6, before 4.15.5.

  5. CVE-2026-64611 7.5 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel() function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially crafted printer advertisement, leading to denial of service.

  6. CVE-2026-59678 7.1 Élevée

    Linux-Gaming PortProtonQt

    An Incorrect Authorization vulnerability in Linux-Gaming PortProtonQt allows any users to mount and unmount arbitrary file systems and modify the network configuration via NetworkManager. This issue affects PortProtonQt before 0d0f0950ebd948cdf82e8c3e1ebd2bcb9b8bafbe.

  7. CVE-2026-59677 6.8 Moyenne

    SELinuxProject selinux

    A Missing Authorization vulnerability in selinux policycoreutils seunshares allows a user that is running in unconfined context to kill e.g. root-owned processes running also in unconfined context This issue affects policycoreutils through 3.10.

  8. CVE-2026-59676 5.8 Moyenne

    SELinuxProject selinux

    A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in seunshare of selinux policycoreutils allows a user calling seunshare that is running in the unconfined SELinux domain to delete arbitrary root-owned files, This issue affects policycoreutils through 3.10.

  9. CVE-2026-64600 7.8 Élevée

    Linux · Linux linux kernel

    In the Linux kernel, the following vulnerability has been resolved: xfs: resample the data fork mapping after cycling ILOCK xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode, a data fork mapping, and a cow fork mapping. Unfortunately, these two helpers cycle the ILOCK to grab a transaction, which means that the mappings are stale as soon as we reacquire the ILOCK. Currently we refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but we don't refresh the data fork mapping beforehand, which means that the xfs_bmap_trim_cow in that function queries the refcount btree about the wrong physical blocks and returns an inaccurate value in *shared. If *shared is now false, the directio write proceeds with a stale data fork mapping. Fix this by querying the data fork mapping if the sequence counter changes across the ILOCK cycle.

  10. CVE-2026-6390 6.8 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in GNU nano's multi-buffer error message handling. When a user opens multiple files at startup and one triggers an ALERT-level error, a specially crafted filename containing printf format specifiers can be reinterpreted. This format string vulnerability may allow an attacker to achieve stack information disclosure, cause a denial of service (crash), or potentially perform arbitrary memory writes.
