The Classic BR/EDR L2CAP signaling handlers l2capbrconfreq and l2capbrconfrsp in subsys/bluetooth/host/classic/l2capbr.c validated the minimum command size against buf-len the bytes remaining in the whole received PDU instead of len the per-command data length from the L2CAP signaling header...

glibc: glibc: Application crash or uninitialized memory read via crafted DNS response

A flaw was found in glibc GNU C Library. The deprecated functions nsprintrrf, nsprintrr, and fpnquery do not properly validate the length of RDATA Resource Record Data in a DNS Domain Name System response when processing specific record types like LOC, CERT, TKEY, or TSIG. A remote attacker could...

USN-8575-1: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

CVE-2026-64191

In the Linux kernel, the following vulnerability has been resolved: i2c: stub: Reject I2C block transfers with invalid length The I2CSMBUSI2CBLOCKDATA case in stubxfer uses data-block0 as the transfer length. The existing check only clamps it to avoid overrunning the chip-words256 register array,...

xrdp is an open source RDP server. In versions 0.10.6 and prior, a n issue was discovered where the software fails to properly validate the totalLength field within the RDP protocol control header during packet reception. An unauthenticated remote attacker can exploit this vulnerability by sendin...

CVE-2026-55645

xrdp is an open source RDP server. Versions 0.10.6 and prior contain a vulnerability concerning the processing of Client Control PDUs. During the RDP connection sequence, the parser does not perform sufficient length validation before reading specific data fields from the network stream. A remote...
