CVE-2026-64548

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...

Uint shift operations: incorrect overflow flags and truncated shift amounts

Uint::overflowingshl/overflowingshr returned false-negative overflow flags. overflowingshl missed bits shifted above BITS but within the top limb non-limb-aligned widths such as U160, and limbs wholly discarded by shifts = 64; overflowingshr missed wholly discarded low limbs. Shifted values were...

Uint::overflowing shl/overflowing shr returned false-negative overflow flags. overflowing shl missed bits shifted above BITS but within the top limb non-limb-aligned widths such as U160, and limbs wholly discarded by shifts = 64; overflowing shr missed wholly discarded low limbs. Shifted values...

PT-2026-3286

Sandboxie 5.49.7 contains a denial of service vulnerability that allows attackers to crash the application by overflowing the container folder input field. Attackers can paste a large buffer of repeated characters into the Sandbox container folder setting to trigger an application crash...

CVE-2021-47784

Cyberfox Web Browser 52.9.1 contains a denial of service vulnerability that allows attackers to crash the application by overflowing the search bar with excessive data. Attackers can generate a 9,000,000 byte payload and paste it into the search bar to trigger an application crash...

CVE-2025-5917 Libarchive: off by one error in build_ustar_entry_name() at archive_write_set_format_pax.c

A vulnerability has been identified in the libarchive library. This flaw involves an 'off-by-one' miscalculation when handling prefixes and suffixes for file names. This can lead to a 1-byte write overflow. While seemingly small, such an overflow can corrupt adjacent memory, leading to...

kernel: ext4: dax: fix overflowing extents beyond inode size when partially writing

An inode corruption flaw was found in the Linux kernel's Ext4 file system functionality related to how a user can interrupt a write using the daxiomaprwfunction. This flaw allows a local user to make non-fatal mistakes with Ext4, leading to a file system denial of service...

Linux Distros Unpatched Vulnerability : CVE-2022-48744

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net/mlx5e: Avoid field-overflowing memcpy In preparation for FORTIFYSOURCE performing compile-time and run-time field bounds checking for memcpy, memmove, and...

CVE-2024-50015

CVE-2024-50015 affects the Linux kernel ext4 dax path. In ext4/dax, the loop in dax_iomap_rw() can copy data after the process is signalled and then update the inode size, causing written extents to exceed the inode size (e.g., 2M vs 4M) and fsck to report inconsistencies. The referenced fixes tr...
