CVE-2026-98584

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix potential stack infoleak in emtextdump emtextdump allocates struct tcfemtext on the stack without zeroing it. strscpy writes the algorithm name and a NUL terminator into conf.algo, leaving the remaining bytes...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.17 contains security vulnerabilities. These vulnerabilities stem from the fact that emtextdump does not zero the stack when allocating a struct tcfemtext; the strscpy function writes the algorithm name and NUL terminator, but the remaining bytes are not initialized...

DEBIAN-CVE-2026-98232

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Validate MODE SENSE lengths in scsicdlenable scsicdlenable uses length fields returned by MODE SENSE to locate the ATA feature mode page in a 64-byte stack buffer. A target can report a total length shorter than its...

CVE-2026-52937

In the Linux kernel, the following vulnerability has been resolved: tap: fix stack info leak in tapioctl SIOCGIFHWADDR In the SIOCGIFHWADDR path, tapioctl copies 16 bytes of an uninitialised on-stack struct sockaddrstorage to userspace via ifrhwaddr, but netifgetmacaddress only writes safamily an...

CVE-2026-52937

CVE-2026-52937 concerns the Linux kernel where the tap_ioctl() path handling SIOCGIFHWADDR leaks kernel stack contents by copying 16 bytes of an uninitialised sockaddr_storage to userspace. Specifically, netif_get_mac_address() writes only sa_family and dev->addr_len (6 bytes), leaving sa_data...
