In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush cache for PASID table before using it When writing the address of a freshly allocated zero-initialized PASID table to a PASID directory entry, do that after the CPU cache flush for this PASID table, not before i...

CVE-2026-45859

The CVE-2026-45859 entry describes a Linux kernel netfilter nfnetlink_queue issue where a shared-unconfirmed nf_conn entry is not checked before segmentation, causing UDP packets to be dropped instead of queued when F_GSO is not set and a GSO packet arrives. The regression arose due to the check ...

CVE-2026-45859 netfilter: nfnetlink_queue: do shared-unconfirmed check before segmentation

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkqueue: do shared-unconfirmed check before segmentation Ulrich reports a regression with nfqueue: If an application did not set the 'FGSO' capability flag and a gso packet with an unconfirmed nfconn entry is...

CVE-2026-45858

In the Linux kernel, the following vulnerability has been resolved: ext4: don't zero the entire extent if EXT4EXTDATAPARTIALVALID1 When allocating initialized blocks from a large unwritten extent, or when splitting an unwritten extent during end I/O and converting it to initialized, there is...

CVE-2026-45857 scsi: csiostor: Fix dereference of null pointer rn

In the Linux kernel, the following vulnerability has been resolved: scsi: csiostor: Fix dereference of null pointer rn The error exit path when rn is NULL ends up deferencing the null pointer rn via the use of the macro CSIOINCSTATS. Fix this by adding a new error return path label after the use ...

CVE-2026-45857

Affected software: Linux kernel (scsi: csiostor). Issue: dereferencing a null pointer rn in the error path when rn is NULL due to macro CSIO_INC_STATS. Root cause: missing safe control flow after macro usage. Impact: potential null-pointer dereference in the SCSI path; no exploitation details pro...

CVE-2026-45855 ata: libata-scsi: avoid Non-NCQ command starvation

In the Linux kernel, the following vulnerability has been resolved: ata: libata-scsi: avoid Non-NCQ command starvation When a non-NCQ command is issued while NCQ commands are being executed, atascsiqcissue indicates to the SCSI layer that the command issuing should be deferred by returning...

CVE-2026-45855

CVE-2026-45855 — Linux kernel (ata: libata-scsi) forward progress fix for Non-NCQ starvation Impact: The issue occurred when a host adapter with multiple submission queues faced constant NCQ traffic, potentially starving non-NCQ commands due to requeueing behavior in ata_scsi_qc_issue(). Root cau...

CVE-2026-45854 crypto: inside-secure/eip93 - unregister only available algorithm

In the Linux kernel, the following vulnerability has been resolved: crypto: inside-secure/eip93 - unregister only available algorithm EIP93 has an options register. This register indicates which crypto algorithms are implemented in silicon. Supported algorithms are registered on this basis...

CVE-2026-45851 efi: Fix reservation of unaccepted memory table

In the Linux kernel, the following vulnerability has been resolved: efi: Fix reservation of unaccepted memory table The reserveunaccepted function incorrectly calculates the size of the memblock reservation for the unaccepted memory table. It aligns the size of the table, but fails to account for...

CVE-2026-45850

CVE-2026-45850 relates to the Linux kernel’s IPVS handling of IPv6: protocol checksum validation can fail when IPv6 extension headers precede the protocol header. The fix uses iph->len as the offset rather than the previous value, addressing the miscalc that allowed incorrect checksums. Affect...

CVE-2026-45850 ipvs: skip ipv6 extension headers for csum checks

In the Linux kernel, the following vulnerability has been resolved: ipvs: skip ipv6 extension headers for csum checks Protocol checksum validation fails for IPv6 if there are extension headers before the protocol header. iph-len already contains its offset, so use it to fix the problem...

CVE-2026-45849 net: mscc: ocelot: add missing lock protection in ocelot_port_xmit_inj()

In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: add missing lock protection in ocelotportxmitinj ocelotportxmitinj calls ocelotcaninject and ocelotportinjectframe without holding the injection group lock. Both functions contain lockdepassertheld for the...

CVE-2026-45847

The CVE-2026-45847 entry describes a Linux kernel issue where WARN_ON_ONCE was triggered while accessing the forward path array. The fix removes WARN_ON_ONCE to mitigate the risk, noting that while unlikely, added support for IPIP tunnels increases the chance of encountering the warning if a suff...
