fkie_cve-2022-41858

A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information.

OESA-2022-2133 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c has an integer wraparound via L2CAP_CONF_REQ packets.(CVE-2022-45934)

There are null-ptr-deref vulnerabilities in drivers/net/slip of linux that allow attacker tocrash linux kernel by simulating slip network card from user-space of linux.[Root cause]When a slip driver is detaching, the slip_close() will act tocleanup necessary resources and sl->tty is set to NULL inslip_close(). Meanwhile, the packet we transmit is blocked,sl_tx_timeout() will be called. Although slip_close() andsl_tx_timeout() use sl->lock to synchronize, we don`t judgewhether sl-> tty equals to NULL in sl_tx_timeout() and thenull pointer dereference bug will happen.(Thread 1) | (Thread 2)| slip_close()| spin_lock_bh(& sl-> lock) sl-> tty = NULL //(1)sl_tx_timeout() | spin_unlock_bh(& sl->lock)spin_lock(& sl-> lock);tty_chars_in_buffer(sl-> tty)|if (tty-> ops-> ..) //(2)synchronize_rcu()We set NULL to sl-> tty in position (1) and dereference sl-> ttyin position (2).(CVE-2022-41858)

A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges.(CVE-2022-4095)

SSA-202008 — SSA-202008: Multiple Vulnerabilities in Ruggedcom Rox Before V2.17.0

An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgroups knob) to prevent this sort of privilege escalation. GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey. remember_Ktype in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM). This can occur during execution of cxxfilt. binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to be exploitable via Local. This vulnerability appears to have been fixed in after commit 3a551c7a1b80fca579461774860574eabfd7f18f. libseccomp before 2.4.0 did not correctly generate 64-bit syscall argument comparisons using the ar…
